April 24, 2020, 08:28	Integration to solve	#1
siw Senior Member Stuart Join Date: Jul 2009 Location: Portsmouth, England Posts: 733 Rep Power: 25	I have made a mistake in an integration by parts I was doing. We engineers like a little problem to solve. Would appreciate the correct answer as I'm not spotting my mistake. $v = \int A e^{(-\lambda t)} \sin(\frac{\pi}{D} t) dt$ evalute constant of integration, C, at t = 0 where v = 0. I'll recheck to see where my error is. Thanks.
