1. The problem statement, all variables and given/known data F(s) = s/((s-1)(s^2+1)) F(s) = (s/(s^2+4s+5))(e^(-3s)) 2. Relevant equations Don't believe there are any. 3. The attempt at a solution Not particularly sure. I can solve ((s-2)(e^-s))/(s^2-4s+3), but seem to be having problems with these.
