Homework Statement
f(t) = (1/(a^2))(1-e^-at - ate^-at)
Homework Equations
f(t) = (1/a)(1-e^(-at))
F(s) = 1/s(s+a)
f(t) = t e^(-at)
F(s) = 1/(s+a)^2
The Attempt at a Solution
F(s) = (1/s(s+a^2)) - (1/(s+a)^2)Totally lost now, but I think this is wrong anyway, can anyone help me please. I know the answer is
F(s) = 1/(s + a)^2
but I have no idea why.
Kind Regards
Rob K
