Series (mathematics) - Wikipedia, the free encyclopedia
In mathematics, given an infinite sequence of numbers {  a n  }, a series is informally the result of adding all those terms together: a 1  +  a 2  +  a 3  + · · ·. These can...

What exactly does the convergence of an infinite series tell us? What does it mean? The goal of this tutorial is to guide you through the processes used to analyze the convergence of an infinite series, and to uncover its importance in relation to other areas of mathematices.

Geometric series - Wikipedia, the free encyclopedia
In mathematics, a geometric series is a series with a constant ratio between successive terms. For example, the series is geometric, because each term except the first can be obtained by multiplying...

In this tutorial, we review some of the most common tests for the convergence of an infinite series $$ \sum_{k=0}^{\infty} a_k = a_0 + a_1 + a_2 + \cdots $$ The proofs or these tests are interesting, so we urge you to look them up in your calculus text.

We say that an infinite series with a sum converges. Some series don't converge, like 1 + 1/2 + 1/3 + 1/4 + ..., the harmonic series.. To see that the partial sums go off to infinity, note that we have 1 and 1/2 and then ;

+ 1/2 n + ..., which is defined and equal to 2. When the sum of an infinite series is finite and definable, then that series and its corresponding seqeuence converge. Otherwise, the series and its corresponding sequence diverge.
