anybody know how to integrate...
I do, but it's a toughie. You do it by integrating by parts. http://www.math.hmc.edu/calculus/tutorials/int_by_parts/ . But since it is a product of three terms, you have to expand the formula in the link to handle three terms. You are in for a pile of algebraic manipulation if you try to do this one. Best to look it up in a table of integrals and don't reinvent the wheel again.
I guess you are trying to transform t*cos(wt) in S domain! You can get hint from proof of Laplace transform of function's derivative.
try this as a check on your method:
