Integral Practice: U Substitution Walk Through

In this video we go over an example problem integral involving u substitution step by step. The problem is x^2 * e^(-x^3) . Note that when using the u-sub technique we can change the bounds of integration to match "u" as a variable, or we can use the same bounds of integration if we substitute our value for x back in after integrating.
