2018年11月7日 · I'm looking for definite integrals that are solvable using the method of differentiation under the integral sign (also called the Feynman Trick) in order to practice using …

2019年5月7日 · I thought I'd use Feynman's Method because I was able to solve this integral using the same method:

2017年4月18日 · Feynman's trick is a very useful tool in evaluating certain integrals for which a useful antiderivative is unavailable. The challenge is always finding a suitable way forward.

Feynman observed that any such number can be uniquely represented as a product of numbers of the form 1 +2−k 1 + 2 − k, where k k is an integer. Testing each of these factors in a binary …

In " Surely You're Joking, Mr. Feynman!," Nobel-prize winning Physicist Richard Feynman said that he challenged his colleagues to give him an integral that they could evaluate with only …

2020年6月11日 · Edit: ah I see many people already beat me to it, I'm slow at writing LaTeX haha. The way I like to think of Feynmans trick (which is just a special case of the Leibniz rule for …

I tried to solve the gaussian integral with Feynman's technique for integration, and now I'm stuck. Here's what I've done:

2018年1月29日 · I heard that the equivalent integral: − ∫∞0 x ex − 1dx can be done using Contour integration (I never studied this). Also that sometimes "Leibniz integral rule" is used instead of …

2020年11月10日 · While watching this video, he says that $$\\lim_{b\\to\\infty}\\int_0^\\infty \\frac{\\sin x}{x}e^{-bx}dx\\to 0$$ since the integrand tends to $0$. However I think that it must …

2020年12月29日 · Setting a = π, c = 441 a = π, c = 441, and multiplying by π π gives exactly 4 4. † † In this case, it's not clear if the 'simplified' integral is actually simpler to do on paper. Still, …
