This sounds like your interest is closer to Engineering. Engineering is application of science, you will apply some of the Physics you learn depending on the field of Engineering you eventually choose. So you won't completely detach from Physics. Of course there may not be much of research. I'm...

I think I should use this as a guideline for future problems. Both u and v should be elementary functions otherwise integration by parts becomes too messy(perhaps impossible). Yes, that was what I had in mind. That's why I got stuck there. Thanks! That will help me move forward. Thanks...

I ran into an integral while working on response of a signal processing filter, it looks like: \int_{-\infty}^{\infty} x^{2} e^{-x^{2}} dx While trying integration by parts u = x^{2} we get du = 2xdx but can't proceed with dv = e^{-x^{2}} because then v = \int e^{-x^{2}} can't be...
