Understanding Derivatives and the Product Rule

The video tutorial explains how to find the derivative of a function using the product rule. It begins by introducing the concept of derivatives and the product rule, which is used when differentiating the product of two functions. The tutorial then sets up the product rule for a polynomial and an exponential function, and proceeds to find the derivatives using the power rule. After calculating the derivatives, the tutorial demonstrates how to combine like terms and factor the expression to arrive at the final derivative function. The video concludes with a summary of the steps taken to find the derivative.
