    This looks enough like a schoolwork question that it needs to be re-posted in the Homework Help, Calculus & Beyond forum, and you need to show your efforts at working toward a solution.

    Do an "integration by parts" twice. Start by letting [itex]u= e^{-x/2}[/itex] and [itex]dv= sin(ax)dx[/itex]
