Inverse Laplace transforms
Hi guys, I'm really stuck on a problem and would really appreciate some help! I'm trying to find the inverse Laplace transform of a function with complex numbers in the form : 4exp(-s)/(s+5.5-i4.97)

Thank you for any help

Maybe it'll help if you remember \displaystyle \displaystyle \begin{align*} \mathcal{L}^{-1}\left\{ e^{-as}F(s) \right\} = f(t - a)H(t - a) \end{align*}.

Re: Inverse Laplace transforms
Is this the shift in s domain formula? Could you explain how I apply it?
Thank you
