Understanding Derivatives of Composite Functions

The video tutorial explains how to find the derivatives of composite functions Big F of X and Big G of X using the chain rule. It begins by introducing the concept of composite functions and the chain rule, then applies these principles to derive Big F of X, where the inner function is X cubed. The tutorial continues with deriving Big G of X, where the inner function is f of X. The process involves identifying the inner and outer functions, applying the chain rule, and using given values to calculate specific derivatives.
