Understanding Derivatives and the Chain Rule

The video tutorial explains how to find the derivative of a composite function using the chain rule. It begins by introducing the problem and identifying the composite nature of the function. The tutorial then explains how to apply the chain rule by defining two functions, V(x) and U(x), and calculating their derivatives. The process involves substituting U(x) into V(x) and using the chain rule to find the derivative of the composite function. The tutorial concludes with a discussion on simplifying the result.
