Homework Help: Find the inverse Laplace transform?

  1. Aug 19, 2013 #1
    1. The problem statement, all variables and given/known data
    Find the inverse Laplace transform of e^(-3pi*s)/(s^2+2s+3).

    2. Relevant equations
    I know that you're supposed to factor out the e^(-3pi*s) and the other part becomes 1/(s+1)^2+2 but how do you get the answer? I'm confused.

    3. The attempt at a solution
    The answer is y=(1/sqrt(2))u3pie^(-(t-3pi))*sin(sqrt(2))(t-3pi)

    Show your work. According to PF Rules you are not supposed to just ask us to do the problem for you.

    I already did some work in #2 template. I really don't know what to do next.
