1. The problem statement, all variables and given/known data I need to find the laplace transform of f(t)=tcos(t). 2. Relevant equations [tex]\int e^-^s^ttcos(t)dt[/tex] 3. The attempt at a solution I just need help on how to integrate this. I can find the answer easily using the f(t)=tcos(kt) general formula but I wish to find it directly.
