 Author Comment/Response Kameron 04/22/13 10:14pm Hi, I've got a question about how Mathematica handles integration of a shifted delta function. For a delta function shifted by a numerical fraction like: Integrate[DiracDelta[x - 1/2], x] Mathematica outputs -1 + HeavisideTheta[-1 + 2 x] I'm wondering why it taks on the extra -1. Although I understand there should always be an implicit constant of integration anyway, it doesn't make sense to me why mathematica just puts a -1 in the case of shifts by numerical fractions and not in other cases, like: Integrate[DiracDelta[x - 2], x] (which gives) HeavisideTheta[-2 + x] Or even algebraic fractions: Integrate[DiracDelta[x - y/2], x] (which gives) HeavisideTheta[2 x - y] Thanks for any ideas or help you can provide!
