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
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

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