New Thread: Integration By Parts Challenge Claim: Integration By Parts is *never* necessary. In this thread I invite you bring me integrals you think necessitate IBP in order to be evaluated, and I will evaluate them by other means.

This integral can't be done in closed form without bounds.

What kind of solution are you looking for? I can give you an answer as an infinite series

That’s easy then.. bring the exponential upstairs, then write sine in Complex exponentials.. multiply by exp(-ix)/exp(-ix) and then expand 1/(1-exp(-i2x)) as a geometric series and integrate term by term
