Abstract

This paper deals with the mixed quadrature rule of degree of precision eleven for the approximate evaluation of analytic functions through Richardson extrapolation. The efficiency and robust of scheme is verified with three numerical tests. The numerical results by present scheme are compared to the exact as well as existing results. The current results are also compared with different researchers in adaptive mode. The convergence analysis with error bound are also determined.
