Evaluating Definite Integrals by Substitution

Two Methods for Making Substitutions in Definite

Integrals

• “Conveniently” ignore the limits of integration and revisit them at the end of the process.

• Recalculate the limits in the very beginning so you don’t have to revisit them at the end.

Let’s see how does that works without

recalculating limits of integration.
