The product rule is one of the fundamental derivative rules in calculus. It shows you how to take the derivative of the product of two functions: f·g. In this video we will introduce the product rule, talk about common mistakes, and give several examples.
Stay tuned! Bonus features for this video are under development...
Calculus is the mathematical study of curves in the plane, surfaces in space, and other "non flat" shapes. You learn about the derivative, which describes how quickly a curve is changing at a specific point. You will also study the integral, which combines the values of a curvy object over a region. While these may seem like opposite puzzles, they are actually connected! So get ready to leave the world of lines behind as you begin to learn the tools needed to study more fancy shapes.
