Abstract
Gregory formulae based on mixed interpolation are derived. These formulae are expressed as the classical rules corrected by two additional terms. A detailed description of the error term occurring in each formula is given. The derived quadrature rules are tested for some numerical problems, where the efficiency of the modified rules and the importance of the discussed error terms are illustrated.Keywords
