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? princess bautista miss manila

WebTaking derivative and rescaling the integral using change of variable we have: I ′ ( b) = − 2 I ( b). This gives us another impossible to solve constant C in: I ( b) = C e − 2 b without leaving this framework yet again.
