Hello, I was unable to get the rezult of the following simple example (looks like an infinite loop) << Calculus`Limit` Limit[Integrate[q^2*r^2*(Cos[q*r] - Sin[q*r]/(q*r)), r],r -> Infinity]] Another question is the similar integral Integrate[r^2*(Cos[q*r] - Sin[q*r]/(q*r)), {r, 0,Infinity},Assumptions->Im[q]==0] Mathematica gives zero here, but we were expecting something proportional to DiracDelta here.
