All rights reserved Slide Tips on Using Integration by Parts: 1. If you have had no success using substitution, try integration by parts. 2. Use integration by parts when an integral is of the form Match it with an integral of the form by choosing a function to be u = f (x), where f (x) can be differentiated, and the remaining factor to be dv = g (x) dx, where g (x) can be integrated.
