Part II

Indefinite Integrals

In this part . . .

You begin calculating the indefinite integral as an anti-derivative — that is, as the inverse of a derivative. In practice, this calculation is easier for some functions than others. So I show you four important tricks — variable substitution, integration by parts, trig substitution, and integrating with partial fractions — for turning a function you don’t know how to integrate into one that you do.
