Thanks Michael,

I have Derive XM 3.05 - I just checked it again and I was wrong; it
gives the integral, int(1/x^2,x,-1,1) = -2.

Which reminds me again of the fun I have with this.
The serious, smart, gifted and talented calculus students
who accept this absurd result as computer gospel - hilarious!

I'm sorry the '92 doesn't make that mistake too.

Geoff
