Maxima algebraic simplification



Rich,
You're right this is really a cool feature. One I'm exploring and one I am
confused about. If I have two named expression e.g.
	e1:y=-x-3 and
	e2:y=3+4x-x^2
How can I plot them? I've tried
	Plot2d([e1,e2], [x,-3-8])
And get no response. I know this is a newbie issue but I need some help
understanding my error. Is there documentation on 'named expressions'
somewhere?

Ron.

Thank you, this is a cool feature, you can name your expressions.  It's like
a math textbook with numbered equations.  Pretty neat.

Rich

Rich,
This is very interesting to me. I did not realize that Maxima would allow an
expression like the following

 eq:sqrt(x)=x^2-5;

This opens new possibilities.
