Delta function (hard question)

1. The problem statement, all variables and given/known data

Compute ∫[itex]^{∞}_{-∞}[/itex]dx (x²+a²)^-1δ(sin(2x)), without calculating the resulting sum.





2. Relevant equations



This is a very specific integral which ,has a delta function δ operating on sin function



3. The attempt at a solution

Does anyone know this integral ? I haven't seen before any similar examples.
