The chain rule is used to differentiate composite functions. For instance, if f and g are functions, then the chain rule expresses the derivative of their composition. The Problem
Complex Functions
Why?
not all derivatives can be found through the use of the power, product, and quotient rules
let t = 1 + x² therefore, y = t³ dy/dt = 3t² dt/dx = 2x by the Chain Rule, dy/dx = dy/dt × dt/dx so dy/dx = 3t² × 2x = 3(1 + x²)² × 2x = 6x(1 + x²)² anytime you want. This rule allows us to differentiate a vast range of functions. Most problems are average. SURVEY . Use the chain rule to differentiate composite functions like sin(2x+1) or [cos(x)]³.

Basic examples that show how to use the chain rule to calculate the derivative of the composition of functions. The chain rule is a method for finding the derivative of composite functions, or functions that are made by combining one or more functions.An example of one of these types of functions is \(f(x) = (1 + x)^2\) which is formed by taking the function \(1+x\) and plugging it into the function \(x^2\). Hint : Recall that with Chain Rule problems you need to identify the “inside” and “outside” functions and then apply the chain rule. when there is a function in a function. The Chain Rule is a formula for computing the derivative of the composition of two or more functions.
