Intro to u-Substitution
U-substitution is an integration technique that is often used when there is composition of terms in the integrand. These integrals are typically pretty ugly, and u-substitution simplifies the way the integral looks by using a substitution, so that the integral is easier to compute. Typically the choice for ‘u’ is chosen as the inside term in the composition. In this video we explain how u-substitution works, and will follow this video with many more examples.
