vious choice is eq(f, g), but I think that this
is inferior since it is much harder to guess.
sage: solve(x^2 - 2 == 0, x)
as opposed to
sage: solve(eq(x^2 -2, 0), x)
The first is totally clear, and is more similar to mathematical notation...

ymbolics package, and
should expect rather different and more specialized behavior.
I hope that explains some of our reasoning on this somewhat confusing
behavior...

s will be able to share
and invite collaborators on a per-worksheet basis, using a model that is
very similar to the one used by google documents.
William Stein will be teaching a class with high school students very soon,
and he wants to use this new functionality. So everything that you want
should
the way any object gets assigned in python.
Just typing
sage: foo
without defining foo will still raise an exception.

ill not know this already. We could
give them a shortcut for things like symbolic expressions, but tell them how
it works, in general, via the docstring. Easing people in is could be a good
thing.

This is also a really difficult problem in the general case.
