In 12 First Examples we define infinite series and inifnite products, and study some basic examples.
In 13 Convergence Tests we develop theorems (known as convergence tests) to help us determine when a series converges, even if we cannot find its value.
In ?sec-series-limits we look at limits of infinite series, a special case of the iterated limits studied previously.
In 15 Advanced Techniques we take a brief look at some advanced techniques for working with infinite series, including summation by parts and double summation
In ?sec-series-rearrangement we explore the vast differences between conditionally convergent series and absolutely convergent series.
