### Constructing Power Series from Functions 1b - More Geometric Power Series

Continuing with constructions based on the geometric power series, we use partial fractions to find the power series of f(x) = 1/(x^2 + x) centered at x=1. As a second example, we find a series representation for pi based on a power series function for tan^{-1}(x) centered at x=0.
