Use final value theorem to find f(∞) for

Question : Use final value theorem to find f(∞) for \[F\left(s\right)=\frac{3+4s^2+5s}{s\left(s^2+4s+2\right)}\] Solution : Use final value theorem to find f(∞) for \[F\left(s\right)=\frac{3+4s^2+5s}{s\left(s^2+4s+2\right)}\] We need to write the function sF(s) as \[sF\left(s\right)=\frac{3+4s^2+5s}{s^2+4s+2}\] By final value theorem \[f\left(\infty\right)=limit_{s\rightarrow0\ }sF(s)\] Therefore \[f\left(\infty\right)=limit_{s\rightarrow0\ }\frac{3+4s^2+5s}{s^2+4s+2}…
