Error estimation for quadrature formulas based on equally spaced nodes

Mathematical Modelling and Analysis, 2006
The error estimation for quadrature formulas based on equally spaced nodes is discussed in this paper. The error estimates use embedded formulas and they are obtained for Newton‐Cotes and Hermitian quadrature formulas.
