How do I do this for a multivariate polynomial? It says O(.) is not defined...
R.x,y = PolynomialRing(QQ)
f = x^3*y^3 + x^2 * y^4 + x*y + x + y + 1
How can I chop this polynomial up to a certain degree of x and y? I.e. I want
to keep up
Well those paths look suspicious (probably because you changed them). The
paths should be `sage --root` + /local/share/emacs and `sage --root` +
/sage respectively. Really, all I can say is copy what appears in the output
of
sage -f
Is there any plans to make Sage more useful to beginners? To give two
examples from different levels:
1*(2+
This gives SyntaxError: invalid syntax and explanation is ... exec
compile(u'open(___code___.py,w).write(# -*- coding: utf-8 ... ---
what is beginner supposed to do with this?

I don't get the same error, and don't get any response at all until I
close the parenthesis. What's wrong with Syntax
Here's a different approach, which is more efficient, but poses its own
challenges:
sage: I = R.ideal(x^2)
sage: Q = R.quo(I)
sage: f = Q(x^3*y^3 + x^2*y^4 + x*y + x + y + 1)
sage: f
xbar*ybar + xbar + ybar + 1
So, the variables look different, and with reason. But:
sage: %timeit
The following code snippet works, until you uncomment the c=x-a line, at
which point you get the error
TypeError: f() takes exactly 2 arguments (1 given). The line c=x
causes no problems. What's going on?
(Note: I know you don't need that line; this replicates the TypeError in a
more

For 1 variable, I'd do:
R.x = PolynomialRing(QQ)
f = x^4 + x^2 + x^3 + x

Thank you! - that does explain the error.
If I convert back within the function (as below) , it eliminates the error
message, and also seems to work in my real problem. Are there better
ways to do this conversion back (to something compatible with symbolic
expressions) than using
