If I may ask, do you have any book which has solutions of some of these hard integrals so that one can get a knack of ways to solve them than just start from first principles like by-parts ? Nntaleb and his twitter followers also often discuss solutions by methods which were not taught in Calculus 2.
It would be great idea to see one such book if it doesn't exist.
