1. The problem statement, all variables and given/known data 2y'' + y' + 4y = ∂(t-π/6)sin(t); y(0)=0, y'(0)=1/2. 2. Relevant equations Dunno 3. The attempt at a solution The left side of the equation is what's tripping me up. There's nothing on my Elementary Laplace Transforms table that has the Dirac delta function multiplied by another function, or sin(at) multiplied by another function f(t). So what should I do?
