Abstract
Quadrature formulas of the Clenshaw-Curtis type, based on the “practical” abscissasx k=cos(kπ/n),k=0(1)n, are obtained for the numerical evaluation of Cauchy principal value integrals\(\int\limits_{ - 1}^1 {(x - a)^{ - 1} } f(x) dx, - 1< a< 1\).
Zusammenfassung
Die Quadraturformeln vom Clenshaw-Curtis Typ, die auf den “praktischen” Abszissenx k=cos(kπ/n),k=0(1)n, basieren, werden für die numerische Berechnung des Cauchyschen Hauptwerts\(\int\limits_{ - 1}^1 {(x - a)^{ - 1} } f(x) dx, - 1< a< 1\), abgeleitet.
