1. The problem statement, all variables and given/known data
[tex]y''+2y'+3y=sin(t)+\delta (t-3 \pi )[/tex]


2. Relevant equations



3. The attempt at a solution
Left side is just [tex] Y(s)*(s^2+1)-1[/tex]
But I don't know how to deal with the delta function, I made it into just an intergral but I dont know how to intergrate it.

[tex]L[\delta(t-t_0)]=e^{-t_0 s}[/tex]


If I remember correctly that is.
 
thanks=)
