Plenty of people here build Sage on Macs. OS X 10.7 is not supported, but
10.6.7 should be. I don't know if there are significant differences between
Mac OS X 10.6.7 and Mac OS X Server
so Id better not use mac I guess...

Hello,
I wanted to create some video files for my students (we're studying the
wave equation, which begs for animation) and post them on the web where
they can be easily watched. The easiest way to do this is to create
videos in formats understand by browsers that implement the HTML5
tag. (Basica
The rich comparison operators acting on symbolic ring elements/functions
return symbolic equations/inequalities. Otherwise you wouldn't be able to
construct symbolic relations. Note that the cast to bool is funky: If it
returns False, it means "I can't decide".

Thanks for the prompt tips. They were perfect!

Note if you really want to do the things you want to do in the right way you
have to learn about categories, parents, elements and the coercion model in
sage.

z.domain() fails because [0,1] is not a function but a list try:

z.operation() fails because operation expects two arguments but it gets none

z.operation(4,3)

What solution is best for you really depends on how much you expect sage
will get used. I definitly advise you to have your own sage notebook server
running somewhere. And it would be best if that place was accesible from the
WWW so student can also use it from home.

Hi Everyone
I'm just starting to learn Python and want to define a class that represents a
set with a binary operation. In a Mathematica package I co-wrote for abstract
algebra we used the term "groupoid" and I know that this isn't the conventional
definition, but I'm using it below. I've rea
I'd say that if you really want to develop Sage with your students on a
joint computer then you need to have direct access to a Linux machine. Its
not that hard to install, just give it a try. The easiest way to collaborate
is if everybody installs Sage in his own home directory, then does his
I'm trying to decide how and where to install Sage. I'm hoping you
can all give me some guidance (and that this thread will be useful to
other folks in a similar position).
In the past, I have used Sage in three ways:
1) Via the notebook server at sagenb.org
2) Via an account on one of the resea
