Integration with U Substitution (Introduction)

This Calculus 1 video on integration by u substitution explains how to integrate using u-substitution. We describe how to think through the steps of making a substitution for integration using u substitution, making sure that all of the integral is in terms of the new variable. We also work through a couple of basic examples of u substitution integration, explaining how to choose u and find du.
