Infinite Series

Course Material Related to This Topic:

Determining whether a given series converges or diverges.

Three questions which involve finding the sum of a geometric series, writing infinite decimals as the quotient of integers, determining whether fifteen different series converge or diverge, and using Riemann sums to show a bound on the series of sums of 1/n.
