WebApr 18, 2024 · A common integration technique is to employ Feymann's trick. Assume that we have the following function of two variables. ∫ a b f ( x, y) d x. Then we can differentiate with respect to y provided that f is continuous and has partial continuous derivative on a chosen interval. F ′ ( y) = ∫ a b f y ( x, y) d x. Web1 Answer. The first step is to squeeze the denominators using Feynman's trick: I = ∫ 0 1 d x d y d z δ ( 1 − x − y − z) ∫ d d q 2 [ y ( q 2 + m 1 2) + z ( ( q + p 1) 2 + m 2 2) + x ( ( q + p …

In Mathematics, his favorite trick was to use differentiation under the integral sign. Derivatives are structured and easier to analyze than integration, thus Feynman percolated the idea, ‘Why not use differentiation within the integration to make integrals easier to solve?’. hp 68r51ua#aba
