ON USE OF MIXED RULE IN AN ADAPTIVE INTEGRATION SCHEME

摘要

In this paper, we introduce a mixed quadrature rule using Fejer's second rule and Gaussian rule. This rule is taken as the base rule to develop an adaptive integration scheme. Using this scheme, some test integrals have been evaluated. The results are found to be more encouraging as compared to those obtained by using some other quadratures in this i ntegration scheme.
