Yes. But if this is something you are trying to do with Mathematica, or Wolfram|Alpha, and you spell out what you have tried (preferably providing code, or the W|A input you used), then it becomes suitable for this forum. For general math independent of Wolfram technologies there are other forums. I just did a Google search for "where to ask math questions on internet" (but without the quotes) and came up with several hits that look pretty reasonable.
On a distantly related note, are you sure there is a way to separate variables for your DE? (It's been a long time since I've studied the topic so maybe I'm missing something.)
