The two main techniques of integration taught in calculus courses are integration by substitution and integration by parts. This talk will describe and illustrate a third technique of integration, almost never taught in math courses, called differentiation under the integral sign. It can handle integrals that appear inaccessible to simpler methods. The physicist Richard Feynman had great affection for differentiation under the integral sign, writing once "I caught on how to use that method, and I used that one damn tool again and again."

Some familiarity with calculating partial derivatives from multivariable calculus will be assumed.
