Improper Integrals SUGGESTED REFERENCE MATERIAL: As you work through the problems listed below, you should reference Chapter 7.8 of the rec- ommended textbook (or the equivalent chapter in your alternative textbook/online resource) and your lecture notes. EXPECTED SKILLS: Given an improper integral, which either has an infinite interval of integration or an infinite discontinuity, be able to evaluate it using a limit. Know how to determine if such an integral converges (and if so, what it converges to) or diverges. PRACTICE PROBLEMS: For problems 1-13, evaluate each improper integral or show that it diverges. 1.
