Understanding Derivatives and Rules

The video tutorial explains how to find the derivative of a function using the product and chain rules. It begins by identifying the inner functions and then applies the rules to calculate the derivative. The process involves substitution and simplification of the derivative expression, followed by factoring to achieve a simplified form. The tutorial concludes with a discussion on the necessity of algebraic simplification.
