How do I find the derivative of a function?

To find the derivative of a function, you can use differentiation rules and techniques.

To drive a function, it depends on what kind of function it is. For basic derivatives such as x^2, all you do is multiply by the power and take a ways form the power. So the derivative of x^2 is just 2x. But for transcendental functions such as cosx and sinx the derivatives are a bit different

dy/dx for example y=6x^2 , to find dy/dx you multiply the coefficient 6 by the power 2 and then reduce the original power by 1 so the answer is 12x . That is the derivative of the function (y)

The process of determining the derivative of a function is known as differentiation. It is clearly visible that the basic concept of derivative of a function is closely intertwined with limits. Therefore, it can be expected that the rules of derivatives are similar to that of limits. There are various rules to find the derivative of different functions.

In very simple words, the derivative of a function f(x) represents its rate of change and is denoted by either f'(x) or df/dx. Recall that there are different types of functions thus the techniques to find derivative. Types of functions are: Algebraic, trigonometric etc

If you want to find out the derivative of function ,you have to make sure what are the variables in the function,then find the derivative wrt time or position in general case,if there is function then take the derivative of the function in terms of x,y or z,t depends on the function.

Derivative is rate of change of change of function with respect to x . It is denoted by f' (x ) or dy/dx. It is used to calculate the gradient of the line.

The derivative is basically the slope . There are two ways to do this. 1. Find the limit of the function approaching PS and been in from each aside 2. Deriv shortcut and then evaluate if you have a value for x. If not, email me a picture of the original problem please, and I will reply as quickly as I can.

Let's use Y = X^2 as an example, to find the derivative of that function, you multiply the X side of the function by 2 and subtract 1 from the exponent. This is the same for other exponents of X whether bigger or smaller than X^2 Although you can also look up how to do derivatives of other functions too.

To drive something you need should identify problem type either which derivative formula you gonna apply once you know that you could easily solve that by simple derivation like take your question apply function and do it simply.

There are rules for finding derivatives depending upon what type of function you have. All rules are derived using the definition of derivative lim as h approaches zero of f(x+h) -f(x) , divided by h. The derivative is a slope function which gives you a formula for finding the slope of a tangent line to a curve at a particular point. This slope is the rate of change of a function at a particular value of x. If time is the independent variable, then the slope gives the instantaneous rate of change of the function at a particular point of time. It could represent the velocity of a particle at a point in time or acceleration of an object st a given time. The derivative measures the rate of change of any function at a given time. One can analyze properties of functions knowing the derivative..

Basically, we can compute the derivative of f(x) using the limit definition of derivatives with the following steps: Find f(x + h). Plug f(x + h), f(x), and h into the limit definition of a derivative. Simplify the difference quotient. Take the limit, as h approaches 0, of the simplified difference quotient.

For the derivatives, there is various rules according to the expression. So understand the concept of derivative plz send me mail.

Basically, we can compute the derivative of f(x) using the limit definition of derivatives with the following steps: 1. Find f(x+h) 2. Plug f(x+h), f(x), and h into the limit definition of a derivative 3. Simplify the difference quotient 4. Take the limit, as h approaches 0, of the simplified difference quotient

To find the derivative of a function you need to understand what derivative of a function is . Let a function be denoted F and let X be a variable F(x) is a function. The derivative of f(x) is given as F’(x). Let the derivative of the function F(x) be denoted F’((x), then for each value of X the following limit exist . F’(x) = F(x+h) - F(x)/h where h limits to zero This above expression is the derivative of a function

Hello Paul, I can help you find the derivative of a function and give you a comfortable platform to learn mathematics in an easy way. Basically, the derivative of a function means you are getting the slope of the function. A function can be expressed in terms of an equation(linear, quadratic, etc). You can contact me

Simplify the difference quotient. Take the limit as h approaches 0 of the simplified difference quotient.

To find the derivative of a function, you apply the rules of differentiation. Here are the basic rules you'll need: 1. Power Rule: For any function f(x) = x^n, where n is a constant, the derivative is f'(x) = nx^(n-1). 2. Sum Rule: For functions f(x) and g(x), the derivative of their sum is (f(x) + g(x))' = f'(x) + g'(x). 3. Product Rule: For functions f(x) and g(x), the derivative of their product is (f(x) * g(x))' = f'(x) * g(x) + f(x) * g'(x). 4. Quotient Rule: For functions f(x) and g(x), the derivative of their quotient is (f(x) / g(x))' = (f'(x) * g(x) - f(x) * g'(x)) / (g(x))^2. 5. Chain Rule: For a composite function f(g(x)), the derivative is f'(g(x)) * g'(x). Identify the type of function you're working with, apply the appropriate differentiation rule(s), and simplify the result to find the derivative.

Mathematically derivative of a function means slope of a tangent at a particular point. Or we can define f'(c) = lim h tends to zero f( c+h) - f(c)/h, provide the limit exists

add one to the power and use it to multiply the original function. If the function is exponential differentiate the power and use the result to multiply to the original function

Using differentiation technique, you may simply do but for this you have to learn basics, you need me then kindly messge

Hi Paul, to find the derivative of a function first Identify the dependent and independent variable in the given function e.g y = x + m here y is the dependent variable and x is the independent I.e you can't get the value of y if you don't know x but if you get the value of y x will not still be determined NB: m is a constant I.e it is known. Now if you are given a function y=x+m for instance the derivative is written as dy/dx= 1. Why 1? There is a general equation that states that if y=x ^n then dy/dx= nx^x-1 and the derivative of a constant is zero. I hope you grab a little understanding from here if you will like a 5min class to break it down properly send a mail to you will be invited for a live session via Google meet or Zoom.

To find the derivative of a function say f, we apply the concept of limit. f'(x)=lim((f(x+h)-f(x))/h) as h approaches 0

Derivative of 3x^2 = (2*3)x^(2-1) = 6x Derivative of 3x = (1*3)x^(1-1) = 3 Derivative of 3 = 0

Hi, threre are many ways to find the derivative of a function like by defination, by some appropriate formula etc. Please contact me for detailed discussion. Regards

Use dy/dx formular

If you could give an example I could show you thr simple steps to do it For example if you have y=4x^2 To find the derivative of this function you have to find dy/dx First you have to multiply the power by the multiple of x In this case 4 x 2 = 8 Then you can write Dy/dx= 8x As simple as! Let me know if you come across more complex examples

Y=f(x)

Derivative of a Function: ‌The derivative of a function is defined as the instantaneous rate of change of a function at a specific point. ‌The derivative gives the exact slope along the curve at a specific point. ‌The derivative of the function is represented as dy/dx, which means the derivative of y with respect to the variable x.

You can find the derivative of a function by differentiating from the first principle, you can also apply direct differentiation method. I'm sure a class demonstration can help you further understand the methods.

For example, dy/dx of x^n = nx^n-1. The derivative can also be referred to as ''change''

Derivative can be easy or complex. I start teaching derivative from basic rule. Then progress step by step to a point that derivative becomes the simplest thing in Maths for you.

Hello Paul; There are many different methods and types of derivations. Which you can solve that particular methods to easily get your solution with proper understanding. You can contact me for any doubts or queries. Thank you. Best RegardsDeepak Rajput (find tutors)

Well...this depends on the kind of question at hand. If it's explicit function i.e just one variable. You'll multiple the coefficient by the exponent leaving the variable and removing 1 from the exponent. E.g if y = x^3. Here, dy/dx = 1(3)x^3-1= 3x^2. This can also be done using the first principal approach by adding small increment and performing necessary operations.If it's more than one variable, we'll solve it explicitly w.r.t a particular variable. We also have function of a function (chain rule), the product rule, the quotient rule to mention a few. Thanks

Well to find derivative requires some techniques which become easier once you do more practice. The trickier part is when you are asked to find derivative but doesn't exist like absolute value of x at x=0. You want know more reply to this we can sort out something. Funny fact many people think integral is inverse of derivative but in reality it's not as some advanced topics like divergence and curl of functions are derivatives which are defined using integral. Moral of the story don't think derivatives and integrals as algebraic manipulations. Think like pure mathematician to enjoy your further study. I know you won't stop there after knowing how to evaluate derivatives. You'll need more and I can help with that. Good luck

Step 1 : We find f(x+h) by substituting x+h in place of x and simplify where possible. Step 2 : Now Find the difference between f(x+h) and f(x). Simplify as much as possible. Step 3 : Divide the expression in step 2 with h. Step 4 : Finally we substitute h=0.

Hi Paul for derivative you should have to focus on rules according derivative so it will become easier for you

Either from first principles using limits, or by using theorems like the product or quotient theorems etc.

A derivative is a rate of change of a function, its slope (+, -, or zero). Different functions (polynomials, trigonometric, exponential, logarithmic etc) have some simple rules to follow, with polynomials being the easiest e.g. X2 ( or X squared, with power =2) is in two steps: multiply by the power (i.e. 2), and subtract 1 from the power (2-1=1). Answer becomes 2X. Similarly 2X3 (2 X cubed) is 2*3*X2 = 6X2 (6 X squared), the cubed power of 3 now becomes the squared power of 2. We can work through more complex examples in the same way.

You cab find the derivative of a function by remembering some basic rule .For example derivativative of any function x^n is nx^(n-1).Derivative of x^1 is 2x

The definition of the ordinary derivative is complicated. Use the laws of differential calculus. They are the sum and difference rule, the product rule, the quotient rule, the power rule, and the chain rule.

Basically, we can compute the derivative of f(x) using the limit definition of derivatives with the following steps: Find f(x + h). Plug f(x + h), f(x), and h into the limit definition of a derivative. Simplify the difference quotient. Take the limit, as h approaches 0, of the simplified difference quotient.

You can find the derivative i.e if algebraic function is there first multiply the power with the function and reduce the power with 1 in problem function.

You have to learn some techniques and rules to find derivative of every kind of function. Feel free to contact me to learn about it.

You will find the derivative of a function by decreasing the power of variable each time and constants will be zero. Like d/dx (2x+3) = 2 Because x will be 1 and 3 becomes zero.

To find the derivative of a function, you can follow these general steps: Identify the function: Let's say you have a function, denoted as f(x), for which you want to find the derivative. Understand the notation: The derivative of a function is commonly represented using prime notation (') or by using the notation dy/dx, where y represents the dependent variable and x represents the independent variable. Use differentiation rules: Apply the appropriate rules of differentiation based on the type of function you're working with. Here are some common rules: Power Rule: If you have a function of the form f(x) = x^n, the derivative is given by f'(x) = nx^(n-1). Constant Rule: If you have a constant value, such as f(x) = c, the derivative is f'(x) = 0. Sum/Difference Rule: For functions in the form f(x) = g(x) ± h(x), the derivative is f'(x) = g'(x) ± h'(x). Product Rule: If you have a product of two functions, f(x) = g(x) * h(x), the derivative is given by f'(x) = g'(x) * h(x) + g(x) * h'(x). Quotient Rule: For a quotient of two functions, f(x) = g(x) / h(x), the derivative is f'(x) = [g'(x) * h(x) - g(x) * h'(x)] / [h(x)]^2. Chain Rule: When dealing with composite functions, where f(x) = g(h(x)), the derivative is f'(x) = g'(h(x)) * h'(x). Apply the rules step by step: Identify the type of function and apply the appropriate rule(s) to find the derivative. If the function is a combination of different types, you may need to apply multiple rules in a specific order. Simplify the derivative: After applying the rules, simplify the derivative expression as much as possible. It's important to note that these are just some basic rules, and there are more advanced techniques for finding derivatives of more complex functions, such as trigonometric, exponential, and logarithmic functions. Learning and practicing these techniques will help you become more proficient in finding derivatives.

You can find first-order, 2nd order, 3rd order derivatives easily for "x" function. If I can help you, contact me

In simple term if you got a function f(x)= A times x to the power a plus B x to the power b Plus C times x to the power c, then the derivative of f(x) which is f'(x) will be a times A times x to the power (a-1) plus b times B times x to the power b-1 plus c times C times x to the power c-1. I will explain it clearly when we meet face to face as it is my preferred way of tutoring.

derivative of x is f^1(x) whereby f^1(x) = lim h->0 (f(x + h) -f(x))/h example f(x) = 3x -2 replace x with x + h to be 3(x +h) -2 use the formula lim ( 3(x +h) -2 -[3x -2])/h h->0 lim ( 3x + 3h -2 -3x + 2)/h =3h/h =3 h->0

Hi Paul. There are rules or formulas for every maths question. First you identify the type of function, then you can now apply the derivatives rules. I can show you step by step if you want me to. I'm just a click away.. Evi Ogu.

There are rules to find the derivative of a function, but I can provide you with certain mnemonics that will help to recall and apply these rules

To find the derivative of a function: Identify the function, denoted as f(x). Apply differentiation rules, such as the power rule, constant rule, sum/difference rule, product rule, and quotient rule. Use the chain rule for composite functions. Simplify the expression and evaluate if needed. Practice and familiarity with different functions will enhance your ability to find derivatives efficiently.

Lets take an example: x^3 + 7x^2 + 10 The first thing to know about differentiation is when you add terms together, each term can be differentiated separately In this example that means you differentiate the x^2, then the 7x, then the 10 separately, then add your answers for each of these together To differentiate x^3, you need to multiply by the power, then reduce the power by 1. So multiply by 2 to get 3x^3, then reduce the power by 1 to get 3x^2. Same with 7x^2 - differentiating this would get 14x. With the 10, the rule is if you are differentiating just a number, the derivative is 0. Therefore when you add these together, your answer is 3x^2 +14x

To find the derivative of a function, you can follow these steps: 1. Start with a given function. Let's call it f(x). 2. Choose a point on the function where you want to find the derivative. Let's call it x₀. 3. Select a very small increment, denoted as Δx. This represents a small change in the x-coordinate around the point x₀. 4. Calculate the corresponding change in the function, which is Δf. To do this, evaluate f(x₀ + Δx) - f(x₀). 5. Calculate the derivative by dividing the change in the function by the change in the x-coordinate. The derivative at x₀ is approximately equal to Δf / Δx. 6. To find the exact derivative, you need to take the limit as Δx approaches zero. This is written as: f'(x₀) = lim(Δx → 0) [f(x₀ + Δx) - f(x₀)] / Δx This limit represents the instantaneous rate of change of the function at the point x₀, which is the derivative. 7. Simplify the expression and calculate the limit to find the derivative of the function at x₀. It's worth noting that there are specific rules and formulas for finding derivatives of different types of functions, such as power functions, exponential functions, trigonometric functions, and more. These rules can make the process easier for specific cases. contact me via WhatsApp +254708311652 for a more in-depth explanation

Subtract 1 from the power for each term. And multiply any numbers before an “x” by the old power. For constants (i.e. numbers on their own such as 2) just remove them. E.g. 3x^3 + 4 The derivative would be 9x^2

It's quite simple to find the derivative of a function. First, identify the type of the function(like polynomial, trigonometric etc..) and then use the appropriate formula to find the derivative and you have your answer. If you need more help, feel free to contact me. I would be glad to help!

Derivatives have an easy formula to remember to find the derivative of a function. You can use the power rule, chain rule or product rule depending on how complicated your original function is. It is important to note that the derivative gives you the formula you will be able to use to find the gradient at any point on a curve.

for the first derivative, you must differentiate your equation once. To do this, you multiply the coefficient of x by the power. Then you subtract 1 from the power. An example is 3x^8 1. multiple 3 by 2 to get 6x. 2. minus 1 from the power ^8 to get 7. your final answer is 6x^7

To find the derivative of a function, identify the function, apply differentiation rules, simplify the expression, and interpret the derivative as the rate of change of the function. You can reach for more detailed explanation.

Hello Paul, Divya this side. Derivative of a function is very easy to solve, if we know the different types of rules used in derivation. There are some rules (formulas) are using for solving derivative of a function (Rules were explained below after the example questions). Definition: In mathematics (particularly in differential calculus), the derivative is a way to show instantaneous rate of change: that is, the amount by which a function is changing at one given point. The derivative of a function f(x) is the function whose value at x is f′(x). Example 1: To find the derivative of 2x Solution: 2x = a constant multiplied by x (2 is a constant digit multiplied by a variable x) The derivative of 2x is 2 which can be derived using different methods of differentiation. We can use the power rule, product rule, and first principle of derivatives. Here, we can derive the differentiation of 2x using the formula [cx]' = c [2x]' = 2 Example 2: derivative of 5 f[x] = 5 f[x]=5 is 0. Since 5 is constant with respect to x , the derivative of 5 with respect to x is 0 . Calculating the derivative of a function would become much easier if you use rules/properties as explained below : Sum rule: (af(x)+bg(x))' = af'(x) + bg'(x) Product rule: (f(x)g(x))' = f'(x)g(x) + f(x)g'(x) Quotient rule: (f(x)/g(x))' = (f'(x)g - f(x)g'(x))/g(x)2 Chain rule: f(g(x))' = f'(g(x))g'(x) Using these rules of derivation for different types of function, it is very easy to find the solution (All the rules should be learn well). For more, please contact me. I am happy to help you..

there are different rules to find derivatives of each function

Hi Paul Let say we have f(x)=2x This could also be written as y = 2x Where y = f(x) Solution Therefore; applying the differential operation (not necessarily going through from 1st principle) It becomes; >>> d(f(x))/dx =d(2x)/dx Note: 2x has two materials >>Number known materials and there called constant >>letters are used to represent unknown materials >>>Any operation on constant leads to zero >>>Operation on unknown materials will Another unknown materials tending towards zero. Therefore; This >>> d(f(x))/dx =d(2x)/dx Becomes f'(x) = 2

Typically the derivative of a function y(x) is defined as a limit, as to how the function varies with a small infinitesimal change in x.

Most of the time the power rule works for most cases: f(x) = x^n as long as n<>0 (meaning n does not equal zero) then the derivative of: f(x) = x ^n is as follows below: f'(x) = n * x ^(n-1) For example, if you wish to find the derivative for the function: f(x) = 5 x^3 then using rule above f'(x) = 5 * 3 x^(3-1) next clean up f'(x) = 15 x^2 and your done

You identify the type of function first and then apply the basic techniques for the derivative.

Usually a function will be in the form ax^b, for example 6x^2. To differentiate this the number in front, a, and the number in the indice, b are multiplied and put in front of the new derivative x term, and then the power of the x is dropped by 1, or b falls by 1. ax^b will differentiate to abx^(b-1), and 6x^2 will differentiate to the 12x. For functions which have multiple x components such as 6x^2 + 3x^4 you can differentiate each separately, 12x + 12x^3. This only works for functions in this form.

The first step is simplifying the function by making use of exponential laws and afterwards apply the rules of derivatives

To find the derivative of a function, you can use various differentiation rules and techniques depending on the complexity of the function. Here's a general step-by-step guide to finding the derivative of a function: Start with the function you want to differentiate. Let's call it f(x). Identify the type of function you are working with. Common types include polynomial functions, exponential functions, logarithmic functions, trigonometric functions, etc. The specific rules and techniques you will use depend on the function type.

You use differentiation rules and techniques depending on the type of function.

The derivative of a function can be found using various rules of differentiation. The process depends on the specific function, but here are some basic rules: Power Rule: The derivative of x^n with respect to x is n*x^(n-1). For example, the derivative of x³ is 3x². Constant Rule: The derivative of a constant is zero. If you have a function like f(x) = 5, the derivative f'(x) = 0. Sum/Difference Rule: The derivative of the sum or difference of two functions is the sum or difference of their derivatives. If you have a function like f(x) = g(x) + h(x), its derivative f'(x) = g'(x) + h'(x). Product Rule: The derivative of the product of two functions is the first function times the derivative of the second function plus the second function times the derivative of the first function. For the functions u(x) and v(x), it's (u * v)' = u' * v + u * v'. Quotient Rule: The derivative of the quotient of two functions is the denominator times the derivative of the numerator minus the numerator times the derivative of the denominator, all over the square of the denominator. For the functions u(x) and v(x), it's (u / v)' = (u' * v - u * v') / (v²). Chain Rule: You can each out to me via WhatsApp on +2347068782597

There is no general rule of the derivative of a function because the function in question could be anything and may not suit any one rule. If you want any help with the derivative of a function, you can find my profile here: https://www.findtutors.co.uk/tutor/yajat-shamji

To find the derivative of a function f(x), in simple functions you multiply the number in front of x by the index and then reduce the index by 1. For example 2x^5 would have the derivative 10x^4.

"to do it" = is the example, you want to do... "how" = treat 100 examples for calculating derivatives... Then, you get it "simple" OR better do something else in your life...

Hi there Paul, for simples exponential functions such as x^2 we just multiply x by 2 and minus 1 from the power so it becomes 2x^1 which is 1. So 2x^4 would be... 8x^3.For more help you can get in touch with me

By applying different derivatives rules according to the problem given and function. For example power rule, product rule, etc. You can contact me.

Sure, I can help you with that. The derivative of a function is a measure of its rate of change. It can be found using the limit definition of the derivative, which states that the derivative of a function f(x) at a point x is equal to the limit of the difference quotient as h approaches 0: f'(x) = lim_{h->0} (f(x+h) - f(x)) / h The difference quotient is the expression that represents the change in the value of the function as the input value is changed by a small amount. In other words, it is the slope of the secant line that intersects the graph of the function at the points (x, f(x)) and (x + h, f(x + h)). The limit definition of the derivative can be used to find the derivative of any function, but there are also a number of shortcuts that can be used for common functions. For example, the derivative of the function f(x) = x^2 is 2x, and the derivative of the function f(x) = e^x is e^x. Here are some simple steps on how to find the derivative of a function: Write the function in terms of x. Use the limit definition of the derivative to find the difference quotient. Simplify the difference quotient. Take the limit of the difference quotient as h approaches 0. The derivative of a function is a very important concept in mathematics. It can be used to solve a wide variety of problems, including finding the slope of a tangent line, determining the area under a curve, and finding the maximum or minimum value of a function. I hope this helps! Let me know if you have any other questions.

Derivative of a function gives the slope or gradient of the tangent of the function at any point. There are a lot of different methods to find the derivative of a function. I can teach you all about that.

Hey Paul! Finding the derivative of a function might sound a little tricky at first, but don't worry, I'll explain it in a way that's easy to understand. Imagine you have a function, which is like a magic machine that takes in a number as its input and gives you another number as its output. For example, if you put in the number 3, the machine might give you the number 9 as the output. The derivative of a function is like asking the magic machine how fast its output changes when you change the input just a little bit. In other words, it tells you the slope or steepness of the function at different points. To find the derivative, we use a special mathematical trick called the "difference rule." Here's how it works: 1. First, pick any number you like, let's call it "x." This is the input you'll put into the magic machine. 2. Next, find out what the output is for that number "x." Let's call that output "y." 3. Now, pick another number very close to "x" (like a best friend of "x" who stands really, really close). We'll call this new number "x + h," where "h" is a tiny amount. 4. Find out what the output of the magic machine is when you put "x + h" as the input. Let's call this new output "y + k," where "k" is the output when we use "x + h." 5. Now, calculate the difference between "y + k" and "y." That's like finding how much the output changed when you changed the input just a little bit (by "h"). 6. Finally, divide that difference by "h" (the tiny amount you changed the input by). This gives you the slope or steepness of the function at that particular point. If you repeat this process for many different points close to each other on the function, you'll get a whole new function called the derivative. This derivative function tells you how fast the magic machine's output is changing at every point. And that's it! You've found the derivative of the function. It helps us understand how the function behaves and how it changes as we move along the input values. It's like understanding the speed of the magic machine's answers to different questions. 😊

1. Identify the function's power (n). 2. Multiply the whole function by n. 3. Subtract 1 from the power (n-1). 4. Simplify if necessary. For example, for the function y = 3x^2, the derivative would be y' = 2*3x^(2-1) = 6x. It is a basic to find derivative of function y.

Derivatives are a fundamental tool of calculus. The derivative of a function of a real variable measures the sensitivity to change of a quantity, which is determined by another quantity. Derivative Formula is given as, f 1 ( x ) = lim △ x → 0 f ( x + △ x ) − f ( x ) △ x.

Start by writing f'(x). For example: for simple function like f(x) = 2(x^3) its : f'(x) = 2*3 (x^2) = 6 x^2. So, you bring down the 3 from x cube and times it with the factor(If none there it's 1). Then subtract the power by 1. Remember these steps are only valid on polynomials. There are different formulas to calculate the derivative of logs or trigonometric values.

Sure, I can help you with that. The derivative of a function is a measure of how much the function changes as its input changes. It is often used to find the slope of a line tangent to the function's graph. There are many ways to find the derivative of a function. One way is to use the limit definition of the derivative. This definition says that the derivative of a function f(x) at x = a is equal to: lim_{h->0} (f(a+h)-f(a))/h In other words, the derivative is the limit of the difference quotient as h approaches 0. Another way to find the derivative of a function is to use the power rule. The power rule says that the derivative of x^n is n*x^(n-1). This rule can be used to find the derivatives of many common functions, such as polynomials, exponential functions, and trigonometric functions. There are also many other rules for finding derivatives. These rules can be found in calculus textbooks or online. Here are some simple steps on how to find the derivative of a function using the limit definition: Find f(x + h). Subtract f(x) from f(x + h). Divide the difference by h. Take the limit of the expression as h approaches 0. Here is an example of how to find the derivative of the function f(x) = x^2 using the limit definition: f(x + h) = (x + h)^2 = x^2 + 2x*h + h^2 f(x) = x^2 (f(x + h) - f(x)) / h = (x^2 + 2x*h + h^2 - x^2) / h = 2x*h + h^2 / h = 2x + h lim_{h->0} (f(x + h) - f(x)) / h = lim_{h->0} (2x + h) = 2x The derivative of f(x) = x^2 is 2x. I hope this helps! Let me know if you have any other questions.

Hi Paul The easiest way is as follows mate. Example f(x) = 4x^5 + 3x^4 The method is to bring the power to the front and multiply it to the number at the front and then reduce the power by 1. Answer f'(x) = (4x5)x^5-1 + (3x4)x^4-1 Final Answer f'(x) = 20x^4 + 12x^3 Hope this helps mate. If it doesnt come back to me and I can provide further support. Best Wishes Mr Singh

There is not general answer Paul, it depends on each specific function

first you need to understand what derivative is ? it is another name for gradient , for straight line( linear function ) gradient is constant that is a fixed number but for curves ( any other function ) gradient varies so we need to find a general formula that can give us gradient at any point on the curve , this formula is a derivative , now there are different rules to find that formula for each function .
