Hi,
when trying to compute the intersection points of 2 circles i got
strange results.
Example 1:
c1(x,y)=(x-5)^2+y^2-25; c2(x,y)=(y-3)^2+x^2-9
Hi,
I am currently trying to switch from commercial CAS to sage.
As a physicist I need to handle non-commutative algebras, most notably Clifford
algebras.
I have read that GiNaC is pretty good in that and that sage is using a variant
called Pynac.
Does Pynac have the non-commutative

Hi Dan,
I worked on this. Would you review Trac 8486?

Hi,
A friend of mine wants to factorize symbolicly x^2 - 2 :
sage: p = x^2 - 2
sage: p.factor()
x^2 - 2
Apparently p.roots() gives almost what he wants :
sage: p.roots()
[(-sqrt(2), 1), (sqrt(2), 1)]
So, I just proposed him to do :
sage: Factorization([(x-r,m) for r,m in p.roots()])

Hello,
I get a strange error while constructing permutation from a cycle
decomposition. Is it a bug or not the right way to build a
permutation ?

Hi everyone,I want do this thing as follows in sage, is that
OK?var('x,y,z')f=cos(x)*cos(y)+cos(y)*cos(z)+cos(z)*cos(x)and then I want to
plot f. how can do it in sage?Thanks in advance!regards,YC

Isn't this a 4d plot? Or do you want to plot

Hello all,
I am using a sage notebook interact to generate and display some
random graphs (more specifically a self-created extension of the
graph class with extra properties) and would like to have the chance
to save the output. Usually the notebook makes all defined variables
global and I can

Hi all,
I just installed Sage and now I'm working through the tutorial.
However, inside notebook I'm unable to generate 3d plots: Issuing i.e.
x,y = var('x,y')
plot3d(x^2 + y^2, (x,-2,2), (y,-2,2))
only yields a gray square without any plots. At the right lower corner
of the square there is a
Thank you very much, that was a great help. Is there a way to pickle
user defined types? So that I can, say, email my advisor files
containing the sage objects.

There is a surprising typesetting bug in the sage 4.3.3 notebook
interface, as it is running on sagenb.org, for example. If the Typset
checkbox is ticked and one evaluates something like
6.5/x
one gets
1/x
So any floating point number is convered to 1 when it is divided by a
symbolic variable.

Hi all:
It looks like working with polynomial rings over transcendental field

below? The same computation works in Singular, giving the correct
