Did working over Frac(ZZ['x,y']) speed things up?

That sort of gets my expressions nicer. It doesn't quite solve the issue with
the computation time but works for now.
Would it be too difficult to have such fractions normalized automatically to
some normal form, e.g. monic denominator polynomial, if the coefficient ring is
a field?
Thanks,

I don't think so. Using www.sagenb.org, I got plots [1] of the given
digraphs. On bsd.math, I got similar results [2]. In both cases, some
of the images are cropped so some part of a vertex is cut off. Ticket
#72
Hi:
The latest bug fix for plotting a digraph seems to be
http://trac.sagemath.org/sage_trac/ticket/5620
Using a 10.6.2 mac (and sage-4.3.1.a5), I am finding that (for example)
sage: D = DiGraph( { "A": ["B","C"], "B": ["C","D"], "C":
["B","D","E"], "D": ["E"], "E": ["D"]} )
sage: D.plot()

Am i doing something wrong, or does the example below demonstrate a

Hello,
Please see my published test notebook at: http://www.sagenb.org/home/pub/1408/

I can get this form integrating properly, and resulting with expected

Is there any flexibility on where axis labels are placed? I'd like to
see them under the x axis and vertically along the y. Seems like
there should be more than just axes_labels= tag.
Thanks,

Hi,
I'm working with fraction fields of multivariate polynomials ring with
coefficients in Q. My question is, how do I get cancellation between
numerator and denominator coefficients to work?
Example:
R.=PolynomialRing(QQ, 2)
F=FractionField(R)
f=(x/2)/(y/2)
My question is, how do I get the r

It seems to me I saw information somewhere on how to get:
foo=function('foo',x,y)
latex(diff(foo,y))
To give the 'partial' notation rather than 'D' notation.
I hope that makes sense. The idea is that I'd like something on
the order of "\frac{\partial}{\partial y} foo" ...
Anyway, I can't fi

This is for OS X 10.6. If you're running OS X 10.5.8, you shouldn't
expect this one to work for you.
