do you know the identity \(\huge L^{1}[e^{as}F(s)]=f(ta)u(ta)\) ?

yes. It's this \[\frac{ 2 }{ \sqrt{15} }e ^{t/4}\sin(\frac{ \sqrt{15} }{ 4 }t)\]

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

\(\huge \frac{ 2 }{ \sqrt{15} }e ^{(t+5)/4}\sin(\frac{ \sqrt{15} }{ 4 }(t5))u(t5)\)
