Annotatsiya
Numerous publications are devoted to quadrature formulas; they include the values of derivatives of integrable functions. When, besides the values of function f at points x on T1, the values of its derivatives of some orders are also known, then naturally, with the correct use of all these data, a more accurate result can be expected than in the case of using only the values of the functions.
