A Mixed Quadrature Rule using Clenshaw-Curtis five point Rule Modified by Richardson Extrapolation
ABSTRACT:
A mixed quadrature rule of precision nine for approximate evaluation of real definite integrals has been constructed by blending Clenshaw-Curtis five point rule modified by Richardson Extrapolation and GaussLegendre four point rule. An error analysis for this mixed rule is provided. The efficiency of this rule is highlighted through numerical evaluation of some definite integrals at the end.
