plot2d feedback



Hi all,

I recently found out about version 5.9 and about xmaxima and was very
excited about installing xmaxima on my machine.

I am helping a student prepare for an exam in basic calculus and he
has to plot a lot of functions. Imagine my dismay when I discovered
that

   plot2d(2*(x+1)/(x-1)^2,[x,-5,5]);

puts maxima into an infinite loop! I guess it is not aware of
singularities.

I would myself venture forth into the wonderful world of maxima
internals, but it's been a while since I last used it and I am not a
lisp programmer.

Anyhow xmaxima looks terrific and the plot viewer is a real winner! I
also love the readline support that was absent from the 5.4. RPM.

Best regards,

--
