Homework Help: Inverse of This Laplace Function

  1. Nov 29, 2008 #1
    H(s) = 1/(s^2+9)^2

    My attempt to the solution is not that all impressive. I know i have to use convolution to do it, so far i got this

    H(s)= (1/(s^2+9).(1/(s^2+9)^2

    Can you make that a convolution of two inverse transforms you already know?
