As far as I can tell, Mathics uses Mathematica syntax with an engine that
runs Python SymPy. It's nice looking, but I don't think (comparing Sympy
and FriCAS) that FriCAS has anything to worry about. However, a nice
interface goes a long way to winning people, and the best system in the
to plot two graphs on the same set of axes. Ordinarily,
this could be done, for example, as
plot([x^2-2,x^3-x],-1..2)
but a list of functions is not a legitimate input to jDraw. So how can I
plot two functions together?
Thanks,
Alasdair

Maybe I should compile sbcl 1.3.5 from source (version 1.3.1 is as high as

rlwrap to do command completion, too.
Note that rlwrap keeps histories between sessions, so if you quit FriCAS,
or if your machine suddenly shuts down, you can fire up again and keep on
from where you left off.
