wow, what does Dirac mean?

It is the Dirac Delta function.

It is related to the Laplace Transforms of Impulse Functions.

Is it related to signal processing

It definitely has it's applications in that. I'm using it in differential equations right now.

I would love to help but I don't have my DE book with me sorry

no problem, thanks anyways.

All I can remember is that all Laplace transformations have a table and it should tell you what the integral is, right?

Yes it is in there; however, I don't know what to do with it since the "cos(t)" function is slipped in there.

integration by parts maybe?

I found a solution to my problem..it was quite simple. I don't have a formal proof, but Sal from Kahn Academy in his D.E. lectures justified it for me. L{Dirac(t-c)*f(t)} = exp(-sc)*f(c) Thanks anyways, though.
