[itex]\delta'(g(x))[/itex]. Where [itex]\delta(x)[/itex] is the dirac delta function. Please notice that what I want to evaluate is not [itex] \frac{d}{dx}(\delta(g(x)))[/itex] but the derivative of the delta function calculated in g(x).

If anyone could post a proof, an idea to find the proof or a link it would be greatly appreciated!
