Infinite Sequences and Series: Strategy for Testing Series

Math Easy Solutions

description

In this video I go over further into infinite series and sequences and this time summarize an 8-step strategy for testing any given series for convergence or divergence. The strategy is not to be followed in order as that would be time consuming but rather to compare the type of series being dealt with the steps in the strategy. Since in my earlier videos I went over alternating series, geometric series, p-series, absolute series, and series with factorials or incrementally increasing powers (i.e. to the power of n), this video serves as a good summary and game plan for deciding how to go about tackling each type of series being presented. I also over 6 quick examples illustrating which test to perform.
