Re: Another strange bug in Mathematica 4.0's Integrate


It's funny what the CA-fans argue and don't admit that a bug is a bug.
If I put in

Integrate[Sqrt[r^2-x^2],{x,-r,r},Assumptions->{r>0}]

this is a well defined expression in terms of a real integral. The
square root is positive because the principle value is realised
(according to the online documentation). Further as long as I do not
tell the path of integration it must be a real integral, otherwise
Integrate is not well defined!
