摘要：The formula proposed in this paper provides the method of estimating errors involved in case of evaluation of integrals of single variable. The error associated with a quadrature rule provides information with a difference of approximation. In the proposed formula, the error term indicates precisely how the error depends on the length of the integration interval, and the degree of precision characterizes the class of polynomials for which the quadrature formula produces exacts results
