Integration By Trig Substitution (Sine Example 3)

This trig substitution tutorial video shows a worked example of integration by trig substitution using sine. We show you how to choose your substitution, set up your triangle, and complete the integral using the trigonometric substitution. We also show how to substitute back to the original variable at the end. This is a typical integration technique commonly found in a Calculus 2 or AP Calculus course.
