Construction of a Mixed Quadrature Rule using Three Different Well-Known Quadrature Rules

Debasish Das, Rajani Ballav Dash, Parthasarathi Das

Abstract

This paper deals with construction of a mixed quadrature rule of precision nine by using Gauss- Legendre 3-point rule, Lobatto 4-point rule and Clenshaw-Curtis 5-point rule, each having precision five. This mixed rule is successfully tested on different real definite integrals.
