A note on the error in Gaussian quadrature (Q1186984)

By methods arising from well-known theory of analytic functions, the authors meticulously analyze the error in Gaussian quadrature and derive how the error term may be expressed in terms of a contour integral against a kernel function denoted by \(K_ n(t)\). Furthermore, two methods for computing the coefficients for the Laurent series of \(K_ n(t)\) are given.
