In this lesson we are going to talk about The Chain Rule. The Chain Rule is a formula for computing the derivative of the composition of two or more functions. That is, if f and g are functions, then the chain rule expresses the derivative of their composition f ∘ g (the function which maps x to f(g(x)) in terms of the derivatives of f and g and the product of functions. So, first, we are going to introduce the formulas for The Chain Rule for composition of two and three functions and later on we will see how to actually use them.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
