First off, I hope these images show up - I don't have time to figure out this latex stuff atm, so it's easier just to throw the formulae together in openoffice.
I'm working on the Laplace Transform for

Which is obviously

Now, in case somebody brings it up, I know that we can look up the answer in the table of basic Laplace transforms as

But if I could get off that easy, I wouldn't be asking this question, would I? ;)
My main problem is that I'm fairly rusty on integration, so I'm probably missing something small. I'd picked out

and was attempting the tabular method, but I'm not getting anywhere. It's looking to me like no matter what you pick for u or dv you'll be doing integration by parts forever, since you're stuck with e^t and sin.
Just need some hints to kick start the thought process.
