In Mathematics, his favorite trick was to use differentiation under the integral sign. … WebJul 31, 2024 · The Feynman's integral trick (a.k.a. differentiation under the integral) proves to be a powerful tool when dealing with definite integrals. However, I have been unable to find a similar extension of Feynman's trick in the case of indefinite integrals. Thus, I conclude that such an extension is not probably possible, which begs the question why?

WebMain article: Differentiation under the integral sign. Differentiating under the integral sign is a useful method for evaluating certain integrals which might be harder using other methods. This method of integrating was so frequently used by Richard Feynman that it is often referred to as Feynman's integration trick. WebFeynman proposed the following elementary argument. Consider instead $$f(y):=\int_0^\infty\frac{\sin x}{x}e^{-xy}dx,$$ so we need $f(0)$. Then differentiate …

Differentiation under the integral sign is mentioned in the late physicist Richard Feynman's best-selling memoir Surely You're Joking, Mr. Feynman! in the chapter "A Different Box of Tools".
