Topic: Sequences and Infinite Series
Subtopic: Comparison Tests


There are two different comparison tests used to determine if a series is convergent or divergent. In each your prior knowledge of the convergence or divergence of a basic series is used to compare to in determining the convergence or divergence of a new series. The direct comparison test (a.k.a. simply the "comparison test") involves knowing how the new and old series compare in terms of one being "contained" in the other. The limit comparison test uses the limit of a ratio of the new and old limits.


By the end of this topic you should know and be prepared to be tested on:


Define: comparison test, direct comparison test, limit comparison test
