1. The problem statement, all variables and given/known data Find the inverse Laplace transform of F(s)=5e^(-8s)/(s2+36) 2. Relevant equations 3. The attempt at a solution I know that to find the inverse Laplace transform of this function, I start by factoring out (e^(-8s)) to end up with 5/(s^2+36), and that my final answer will be step(t-8)f(t-8), where f(t-8) is the inverse of 5/(s^2+36). I've checked the Laplace table and I can't find the inverse of this function.
