Understanding Derivatives and the Chain Rule

The video tutorial explains how to find the derivative of a given function using the chain rule. It begins by introducing the concept of derivatives and the specific function to be differentiated. The tutorial then discusses composite functions and the necessity of using the chain rule. It provides a step-by-step calculation of the derivative, including finding the derivative of the inner function and applying the derivative formula for logarithms. The video concludes with simplifying the derivative expression and summarizing the process.
