"Feynman integration trick" - textbooks?
I was quite impressed by the use of the parametric differentiation e.g. in integrating sin(x)/x in https://www.physicsforums.com/showthread.php?t=80735. Can anyone recommend textbooks that cover this use as a strategy in evaluating integrals? Ideally with some elementary problems for getting some practice at this.
