Abstract:Based on the remainder term for Gauss-Legendre quadrature rule, a correction formula for numerical integration over a triangle is proposed. The new formula increases the algebraic accuracy at least two-order in comparison with the original Gauss-Legendra quadrature rules, which were recently derived by Rathod et al. Results obtained with the correction formulae are compared with the existing formulae. It is shown that the correction formula has higher accuracy than the existing formulae. Thus it is of great us… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
