Best ResponseYou've already chosen the best response.1do you know the identity \(\huge L^{1}[e^{as}F(s)]=f(ta)u(ta)\) ?

Best ResponseYou've already chosen the best response.1so, you first need laplace inverse of 1/(2s^2+s+2) right ?

Best ResponseYou've already chosen the best response.1ohh...so you were able to find laplace inverse of 1/(2s^2+s+2) ??

Best ResponseYou've already chosen the best response.0yes. It's this \[\frac{ 2 }{ \sqrt{15} }e ^{t/4}\sin(\frac{ \sqrt{15} }{ 4 }t)\]

Best ResponseYou've already chosen the best response.1yes, thats correct, now just replace, t by 't5' and add u(t5) in the end. using that formula....
