Code:
Integrate[f[qs] DiracDelta'[qs (1 - 1/x)], {qs, -\[Infinity], \[Infinity]},
Assumptions -> 0 < x < 1]
Integrate[f[qs] DiracDelta'[qs - qs/x], {qs, -\[Infinity], \[Infinity]},
Assumptions -> 0 < x < 1]
This is on Mathematica 8 for windows.
The results differ by a sign. They are effective the exact same thing, but due to how I write the insides of the dirac delta I get a different result.
Can anyone replicate this?
