Numerical Analysis - Gauss Quadrature Rule for Integration (#4)

We learn about the Gauss Quadrature Rule or the n-point rule to estimate a definite integral. We use a set of nodes (x values: x_0, ... x_n) and a corresponding set of weights (c_0, ..., c_n) to estimate an definite integral from a=x_1 to b=x_n.
