solve ∫e^-x(cosx)dx

OpenStudy (zehanz):

You will have to use Integration by Parts - twice! First time: it doesn't seem to get you any further. You end up with an integral of e^(-x)sinx. Second time: everything works out fine. Hope you can get started now with this one. I have to go now, so I can't help you anymore today. Sorry!
