QUADRATURE FORMULAS BASED ON RATIONAL INTERPOLATION WITH NODES CHEBYSHEV –MARKOV
Abstract
In the paper we construct a Lobatto-type quadrature formulas on the segment [−1,1] by weight 1 /√1− x 2 by using quasi-Hermite-type rational interpolation with nodes Chebyshev–Markov. The coefficients of quadrature formulas of Lobatto-type were calculated and estimation of their error in particular. We give example of the use of these quadrature formula and compare the rate of approximation of various types of quadrature formulas.
