Math 205 Lecture 23 - More Integration by Substitution and Area between curves

Welcome to lecture 23 of Math 205 - Elements of Calculus 1.

In this lecture, we continue our discussion of integration by substitution with a couple more examples. We also talk about the two methods of evaluating a definite integral when doing substitution (to change the limits, or to not change the limits, that is the question).

We then go into an important application of integrals--finding the area between curves.
