So that's what Knoboo is about? I'm excited!!
Serge, did you know that you can also format whole cells as html by
putting %html at the top of them? You then just write html code in the
rest of the cell and it will be formatted. Use $...$ to have typeset
equations in your html cells. Example:

A slight variation on John's answer: you could also do:
sage: R.=QQ[]
sage: X = matrix( [ [x, y, z], [y, z, x], [z, x, y] ])
sage: Y = X*X^-1
sage: Y = matrix(R,Y)
sage: Y
[1 0 0]
[0 1 0]
[0 0 1]

Thank you Mike and John. It seemed unlikely to me that there was a bug
anyway, but I had to ask. I used the 'simplify_rational' and it worked
perfectly. Also, I noticed that Mike used 'apply_map'. That and lambda
make it look rather close to Lisp; it looks like the more I look at
sagemath, the bet

I have created a spkg to install lp_solve into Sage; it can be obtained at:
http://www.math.unl.edu/~shartke2/files/lp_solve-5.5.0.13.spkg
I have posted to sage-devel suggesting this spkg for inclusion into Sage.
lp_solve includes a linear programming solver (simplex based) and an integer
programm

I'm not sure either, but he could try his luck with openopt:

Thanks for the response. I'll try to use Sage on a more recent system.
Thanks,

I believe that the answer is currently: no, Sage cannot do integer
linear programming. But I could be wrong, if that capability is
hiding in something added since the last time this question came up.
I am not sure what open source code is out there to do that - ?

Could this be related? is this common? why does it happen and how do I

Dear Sage developers,
In the Firefox interface to SAGE, the command
show(integrate(x))
results in
2
x
2
rather than

in fact , a number of quotients and fractions are displayed
incorrectly.
I am using SAGE 3.1.2 VMWare appliance on Windows XP.

Hi,
a question of a colleague from my lab:
can Sage solve linear systems A*x=b, where A is a matrix with positive
integer coefficients, b is a vector with positive integer coefficients,
and the unknown vector x is searched over the positive integers?
I guess this is more or less equivale

Now here is another puzzlement:

#of course that's one line

Hi all,
I'm using a Fedora Core2 based system, which I can't upgrade.
Compilation fails for the latest Sage (3.1.2). I'm not sure how to fix
this error. Any help is appreciated. I'm pasting the relevant lines

Thanks,

Thank you very much.
I moved to 10.5 and it worked very well.
Now, I follow the tutorial!

This does not format things like a_2 very well. What about this one?
def ashow(v):
show(sage.calculus.calculus.var(v)==eval(v))
Show seems to format the equations nicely without explicitly using
latex.
If latex is desired explicitly, the following works, too:
def ashow(v):

Hi,
I am a newbie with Sage, and have been thrilled at the open source
symbolic computation capability. I was wondering if I misunderstood
something, or if this is a bug. I am using "SAGE Version 3.1.2,
Release Date: 2008-09-19 "
First, I define a matrix X.
X = matrix( [ [x, y, z], [y, z, x], [
