What is an Infinite Series?
Monday, Nov 2, 2015
We start with a sequence {an}, n going from 1 to ∞, and define {si} as shown.
The {si} are called partial sums. These partial sums themselves form a sequence.
An infinite series is the summation of an infinite number of terms of the sequence {an}.

Infinite Series Convergence
Monday, Nov 2, 2015
Our goal is to determine whether an infinite series converges or diverges. It must do one or the other.
If the sequence of partial sums {si} has a finite limit as n −−> ∞, we say that the infinite series converges. Otherwise, it diverges.

Polynomial Approximators
Monday, Nov 2, 2015
On of our goals this chapter is to generate polynomial functions that can be used to approximate other functions near particular values of x.
The polynomial we seek is of the following form:
