Question

다음 함수 F(s)에 대하여 f(t)로 알맞은 것은? F(s)=\frac{5s-2}{(s+1)(s-2)^2}

Accepted Answer

f(t)=-\frac{7}{9}e^{-t}+\frac{7}{9}e^{2t}+\frac{8}{3}te^{2t}

Answer

f(t)=3e^{-2t}-te^{-2t} \quad f(t)=\frac{7}{9}e^{-t}-\frac{7}{9}e^{2t}+\frac{8}{3}te^{2t}

Answer

f(t)=-\frac{7}{9}e^{-t}+\frac{7}{9}e^{2t}-\frac{8}{3}te^{2t}

Answer

f(t)=-7e^{-t}+7e^{2t}+8te^{2t}

Answer

f(t)=\frac{7}{9}e^{t}+\frac{7}{9}e^{-2t}+\frac{8}{3}te^{-2t}
