Example Problems For How to Use the Alternating Series Test (Calculus 2)

In this video we look at several practice problems of using the alternating series test to determine if an alternating series converges or diverges. We also look at a couple examples of approximating the sum of a converging alternating series using an error formula.

This video series is designed to help students understand the concepts of Calculus 2 at a grounded level. No long, boring, and unnecessary explanations, just what you need to know at a reasonable and digestible pace, with the goal of each video being shorter than the average school lecture!

Calculus 2 requires a solid understanding of calculus 1, precalculus, and algebra concepts and techniques. This includes limits, differentiation, basic integration, factoring, equation manipulation, trigonometric functions, logarithms, graphing, and much more. If you are not familiar with these prerequisite topics, be sure to learn them first!

I really like the idea of how you put the most important problems a student should know for each calc 2 chapter, like having solved these 8 numbers with good understanding, a student would be able to solve any problem that might come up in a calc 2 test <3!

No calculator…. Prove be taking the derivative to show if it is decreasing
