Understanding Derivatives and the Chain Rule

The video tutorial explains how to find the derivative of a composite function using the chain rule. It identifies the outer and inner functions, applies the chain rule, and calculates the derivative step-by-step. The example involves the exponential function and hyperbolic cosine, requiring the chain rule to be applied twice due to the composite nature of the function.
