1. The problem statement, all variables and given/known data
Determine the function whose transforms are:
fbar(s)=(((1+3e^(-2s))(1-e^(-3s)))/s^2
2. The attempt at a solution
fbar(s)=(1/s^2) + ((3e^(-2s))/s^2) - ((e^(-3s))/s^2) + ((3e^(-5s))/s^2)
I get:
f(t) = t + 3(t-2)H(t-2) - (t-3)H(t-3) + 3(t-5)H(t-5)
Though in my notes the answer is:
f(t) = t + 3H(t-2)t - H(t-3)t + 6H(t-5)t
Is my answer correct or did I make some mistakes?
