This study guide covers u-substitution for simplifying complex integrals. It explains how to choose the new variable (u), differentiate it, rewrite and simplify the integral, evaluate it, and back-substitute. Examples demonstrate u-substitution with both indefinite and definite integrals, including two methods for handling definite integrals: changing the limits of integration or substituting back before evaluating.
