quadrature formulas, the speed of convergence, the polynomials of ChebyshevAbstract
The interpolation quadrature formula for calculation of the integral of a function containing irreparable rupture of the rst kind had been obtained. This formula is exact for polynomials, the degree of which less than the number of interpolation points. The convergence of approximate values of integrals of the exact values of integrals had been shown. The estimates of the convergence rates had been given.
