In two-point Gauss Quadrature Rule approximation Select one. Learn via example how to apply the Gauss quadrature formula to estimate definite integrals. The arguments of the function are not predetermined.
They have degree of exactness 2n 1 and order 2n.
For integrating any third order polynomial the two-point Gauss quadrature rule will give the same results as Simpsons 13 rule. To use the tabulated Gaussian quadrature parameters we must change the interval of integration to 11. Complete Derivation of Two Point Gaussian Quadrature Rule. It is expressed as.
