      Another lesser-known integration trick is "integration by inversion"pic.twitter.com/jZFABkIE7B

      Provided that the domain of integration is [0,∞> or <-∞,∞> in case of e.g. an even function. It does not work for a general domain [a,b].

      Note: dx/x^2=-d(1/x) flipping ∞ and 0 and the integration sign (a bonus ;-)) and substitute: y=1/x and y is dummy and can be replaced by x again;-)

      What about "Feynman's integral trick"?;-)

          Sometimes, you just gotta divide by infinity -- and then multiply by it. It's fine.
