Hi,
There are problems doing arithmetic in SL_2(Z):
S,T = SL2Z().gens()
S*T; # no problem
S^2*T^3;# no problem
S^-2*T^-3; # no problem
but when I multiply two elements with different exponent:
S^-2*T^3;
S^2*T^-3;
T^2*T^-3;
I get a

Is there any way to define a polynomial ring over a sparse quotient
ring?
This works:
sage: p = 5
sage: A. = PolynomialRing(Integers(p))
sage: f = T^2+1
sage: B = A.quo(f)
sage: print B
sage: C. = PolynomialRing(B)
sage: print C

According to http://modular.math.washington.edu/sage/doc/html/prog/node17.html,
this is *not* a (non-canonical) coercion but object

Perhaps this should be exposed as G.spring_layout() (or some other
name). It seems like it might be useful. C

In each case, we use the native format of that package (
sage: G = graphs.PetersenGraph()
sage: sage.graphs.graph_fast.spring_layout_fast(G, iterations=50,
dim=2)

Jason,
your right in so far that the expand tool does not embed a picture.
However, it does also not embed genuine OO formulas. It represents the
formulas as text with special fonts and special formatting and is
therefore restricted to simple formulas.

If you construct a new graph, the position dictionary is not set. You

Isn't there two parts to oolatex? One does embed a picture, but the
other (the expand tool) doesn't, at least from the description.
Thanks,

If you start Sage, x is already defined:
sage: type(x)

Mike,
what data format is used when sage exchanges symbolic math with math
packages like maxima, maple, mathematica? Maybe there is a converter
for one of these formats.

Dear sage community,
I am new to sage, so please forgive me if I am reporting well-known
behaviour here.
When generating multivariate polynomial rings, some (seemingly) odd
things can happen:

Looks interesting. However it does not translate the formula it just
embeds a picture of it.
With html(latex(sage-output) we get html code, right? And MSWord is
among other things also a html-editor capable of reading and writing

I don't have Word, but maybe this might be useful: http://www.chikrii.com/ .
There is no way to get latex for the input since it only makes s
I can do html(latex(sage-output))
What is the best way to import it into MSWord?
And how can I not only create formulas from sage output but also from
input? (i.e. not only from X^2 but also the actual integral(2x) with
integral sign etc.)
Thanks for your help.
