Does anyone know the inverse laplace transformation of the following:

(se^-s)/(s^(2)+1)

pull out the $e^{-s}$ leaving:

$$L^{-1}{ \{ \frac{s}{s^2+1} \}=f(t-a)$$

Now, the e can be converted to a unit step function $U(t-a)$, and f(s-a) should be apparent.

Combine the unit step function with F(s) to get an end result.
