Posted in MTH 361 - Numerical Analysis. By cdrakep on December 9, 2009. Quadrature as used in numerical analysis, is the method by which we integrate our interpolated functions thereby finding a numerical approximation to the integral through a polynomial instead of the potentially hard to find integral of the original or unknown function,.

There are many forms of quadratures available. Each of these methods are in the same form above. The only difference is the choice of. Subject area had been about polynomial interpolation. The integral of the polynomial intepolant. Maybe be used to derive the quadrature formula of. Lets this polynomial integral be denoted as.
