chain rule easy examples The chain rule says d d x f g x f g x g x It tells us how to differentiate composite functions Quick review of composite functions A function is composite if you can write it as f g x In other words it is a function within a function or a function of a function For example cos
Example What is ddx 1 cos x 1 cos x is made up of 1 g and cos f g 1 g g x cos x The Chain Rule says the derivative of f g x f g x g x The individual derivatives are f g 1 g 2 g x sin x So 1 cos x 1g x 2 sin x sin x cos 2 x Note sin x cos 2 x is also tan x cos x or many The chain rule is a formula to calculate the derivative of a composition of functions Once you have a grasp of the basic idea behind the chain rule the next step is to try your hand at some examples Example 1 Let f x 6x 3 and g x 2x 5 Use the chain rule to calculate h x where h x f g x

The Chain Rule formula shows us that we must first take the derivative of the outer function keeping the inside function untouched Essentially we have to melt away the candy shell to expose the chocolaty goodness Then Example PageIndex 7 Combining the Chain Rule with the Product Rule Find the derivative of h x 2x 1 5 3x 2 7 Solution First apply the product rule then apply the chain rule to each term of the product
It is a rule that states that the derivative of a composition of at least two different types of functions is equal to the derivative of the outer function f u multiplied by the derivative of the inner function g x where u g x This There are two forms of the chain rule Here they are Chain Rule Suppose that we have two functions f x and g x and they are both differentiable If we define F x f g x then the derivative of F x is F x f g x g x If we have y f u and u g x then the derivative of y is dy dx dy du du dx

The chain rule states that the derivative of f g x is f g x g x In other words it helps us differentiate composite functions For example sin x is a composite function because it can be constructed as f g x for f x sin x and g x x About Transcript Let s dive into the process of differentiating a composite function specifically f x sqrt 3x 2 x using the chain rule By breaking down the function into its components sqrt x and 3x 2 x we demonstrate how their derivatives work together to make differentiation easier Created by Sal Khan Questions Tips Thanks
Chain Rule Formula 1 d dx f g x f g x g x Example To find the derivative of d dx sin 2x express sin 2x f g x where f x sin x and g x 2x Then by the chain rule formula d dx sin 2x cos 2x 2 2 cos 2x Chain Rule Formula 2 Solution In order to use the rules we already have we must first expand each function as F 1 x 1 2x x 2 F 2 x 1 3x 3x 2 x 3 and F 3 x 1 4x 6x 2 4x 3 x 4 It is not hard to see that
