Feynman's integral trick
WebHypInt — substitutes Hypergeometric2F1 functions by their integral definition. IntegrateByParts, PartialIntegrate — integration by parts for particular Feynman parameter integrals. NPointTo4Point — rewrites IR-finite 1-loop pentagons in terms of box integrals. OneLoopSimplify — simplifies 1-loop Feynman diagram amplitudes WebIn the second episode of season 8 of "The Big Bang Theory," which aired yesterday night, it is stated that one can integrate x 2 e − x by using Feynman's trick of differentiating under the integral. Is this actually true, and if so, how to do it? And is it "better," in any sense, than the usual way of doing it by integration by parts? calculus
