Calculation of Coefficients of the Optimal Quadrature Formulas in W2(7,0) Space

Year: 2025

Type: article

Abstract: In this paper, we construct an optimal quadrature formula in the sense of Sard by Sobolev’s method in the W2(7,0) space. We give explicit expressions for the corresponding optimal coefficients. This formula is exact for exponentional–trigonometric functions.
