Course: Calculus III
Topic: Sequences and Infinite Series
Subtopic: Absolute and Conditional Convergence


As we have seen with the alternating harmonic series (convergent) and the harmonic series (divergent), removing the alternating signs on a convergent series does not necessarily render it convergent too. This is an example of conditional convergence. In this section we study series that converge conditionally and those that converge absolutely. Absolute convergence (ie. involving the absolute value of the terms in the series) implies convergence. Lots of new terminology!


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


Terms you should be able to define: absolute convergence, converging absolutely, conditional convergence, converging conditionally, general strategy using tests on series
