Forming a mixed Quadrature rule using an anti-Lobatto four point Quadrature rule

Bibhu Prasad Singh, Rajani Ballav Dash

Abstract


A mixed quadrature rule of higher precision for approximate evaluation of real definite integrals has been constructed using an anti-Lobatto rule. The analytical convergence of the rule has been studied. The relative efficiencies of the mixed quadrature rule has been shown with the help of suitable test integrals. The error bound has been determined asymptotically

Keywords


Lobatto two point rule, anti-Lobatto three point rule,Fejers three point second rule, mixed quadrature rule.
