Homework Statement


Find the inverse Laplace transform of e^(-3pi*s)/(s^2+2s+3).


Homework 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.


The Attempt at a Solution


The answer is y=(1/sqrt(2))u3pie^(-(t-3pi))*sin(sqrt(2))(t-3pi)
