An n -point Gaussian quadrature rule, named after Carl Friedrich Gauss, is a quadrature rule constructed to yield an exact result for polynomials of degree 2n − 1 or less by a suitable choice of the nodes xi and weights wi for i = 1, ..., n. The modern formulation using orthogonal polynomials was developed by Carl Gustav Jacobi 1826.

Gaussian Quadratures • Newton-Cotes Formulae – use evenly-spaced functional values – Did not use the flexibility we have to select the quadrature points • In fact a quadrature point has several degrees of freedom. Q(f)=∑i=1m c i f(xi) A formula with m function evaluations requires specification of 2m numbers ci and xi • Gaussian ...
