WebJul 20, 2024 · Richard Feynman is considered to be one of the greatest minds in physics, and has won many accolades as a result of his research in areas such as quantum mechanics and particle physics. However, I am interested in knowing about how Feynman first originated what is known as Feynman's Trick in Integral Calculus. WebWe derive one of Euler’s formulas by employing the trick of differentiating under the integral sign. I learned about this method from the website of Noam Elkies, who reports that it was employed by Inna Zakharevich on a Math 55a problem set. Let. F (t) = ∫ ∞. 0. e−tx dx. The integral is easily evaluated: F (t) = 1 t for all t > 0.
