WebIntroduction. If f ( x) and g ( x) are two functions, for instance f ( x) = x 2 and g ( x) = sin. ( x) , we know how to take the derivative of their sum: We also know how to take the derivative of their product: The chain rule now tells us how to take the derivative of their composition, meaning f ( g ( x)) : Intuition using fake algebra.
