>> From: Herman Jaramillo "HJaramillo"
Dear Maple Users:
When I compute the integral of the Dirac delta function between 0 and
infinity using Maple 7, I get "1". When I do it using Mathematica I
get "1/2".
When I try to do it using distribution theory by choosing a test
function which has bounded support on the positive real line and using
the limit from the left and the right of the interval of integration
(epsilon, infinity) as epsilon goes to 0 I get that the integral
should be "0".
Does anyone understand this?. Can somebody tell me where I can I find
a formal proof using distribution theory whether this integral is
1,1/2 or zero?.
Best Regards.
Herman.
