Hi there, Many of the problems on this part of the forum simply boil down to "I don't know how to solve the ODE: <some strange ODE here>" I kind of forgot how to solve many of these problems myself, so I've just been giving people the answer from matlab's dsolve function. Is this considered rude? I would imagine most people are capable of this, so it might seem cheap. I realize it doesn't help the person much if its for a class, since they need to show their work, but it at least let's them see the form of the right answer. Thanks.
