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.
IBP Challenge (3): Not sure how IBP would have helped this one, but an integral challenge nonetheless.

IBP Challenge (4): ∫eˣ sin(x) dx sans Integration by Parts.pic.twitter.com/JlLf9xWh1H
What about this one? $\vec{a}$ is a constant vector, $m>0$, and $r=|\vec{r}|$. The integral is over an infinite volume. It's certainly possible by other means, but IBP takes two lines.pic.twitter.com/FKnukHOYDX
I never said it would be the most convenient :)
