1. The problem statement, all variables and given/known data [tex]y''+y=\delta (t-2\pi )cos(t)[/tex] [tex]y(0)=0,y'(0)=1[/tex] 2. Relevant equations 3. The attempt at a solution The left side is (s^2+1)Y(s)-1=RHS My problem is the fact that cosine is being multiplied by the delta function. I put it in the form of an intergral but I dont know what to do from there.
