Lesson Summary:

In this lesson on improper integrals, we learn how to interpret and evaluate integrals over unbounded and bounded intervals. We define convergence and divergence for these types of integrals, and explore specific examples of each. We also discuss the fundamental theorem of calculus and notation in the context of improper integrals over unbounded intervals. With clear explanations and visual aids, this lesson provides a comprehensive understanding of improper integrals.

Lesson Description:

Integrals over unbounded intervals. Integrals over bounded intervals of functions that are unbounded near an endpoint. Comparison test for convergence/divergence.

This video begins to introduce convergence and divergence of improper integrals using limits. There are several examples shown, including some very useful and strategic examples that will be used in later videos. The comparison test for convergence is also introduced. This is a very important video for understanding the remainder of Calculus.
