Dear Folks,
Pardon for the double-posting since I am unsure which list is more
appropriate.
In section 2.4.1 of the Sage Tutorial, there is a non-linear equation
example from Jason Grout that I tried out, but it failed. Details follow.
My version is built from the Ubuntu jaunty package source

Hm. I've never had any problems using cp; in fact I routinely do it
before running 'sage -upgrade'. Does 'cp -pR' count as "knowing what
I'm doing"?

it is true, I did it manually and the result should be 39.24

The current version just has different bugs compared to what we
ship :)
But it seems that 5.18.x out in April ought to fix some annoying bugs
about asksign which crept into 5.17, so we should try again.

Dear colleagues,

newbie, my apologizes in advance...), and I have to admit that I am
impressed with Sage!!!. I started yesterday, and came along the tutorial
already. I still miss some more documentation...specially relat

Someone will correct me if I'm wrong, but I believe Sage is self
I am updating Sage on OSX 10.5. This is in a computer lab with about
40 machines. There is an existing version of Sage on the machines.
Does the older version need to be uninstalled first?

Hi,
I'm trying to build sage from the source on our cluster.
The cluster is running under SLES9SP3 (all AMD Opterons).
We are normaly using PGI compiler (8.0.X) for fortran. The
installation is using gcc 4.2.1 from /usr/local/bin.
I tried to set F77, F90 and so on and also tried
to set sage_fortr
Dear all,
I had a great idea (so I thought) about upgrading in the background
while the sage server is still running. Here is what I did, but it
didn't work for some reason: In OS X 10.4, I shut down the server
briefly, changed into the sage directory, ran "cp -r * /newdirectory"
and restarted th
I have problems runing sage in a chroot jail.
Sage version: 3.3
I followed what is written in http://www.sagemath.fr/doc/inst/node10.html
After installing the chroot I copied all the sage tree from a former
installation, outside the chroot (may be the problem is here ?)

I can't get it to work. Could you be a bit more specific with the
details (I really have no clue).
The idea is that I upload the file to VMware Player and then load the
file in Sage, right??? Should I do the Data->Upload before I start
Sage? What would the exact syntax be if the Sage-file is i

Dear Supporters,
the following works:
sage: R=PolynomialRing(QQ,['a','x1','y1'])
sage: S=PolynomialRing(QQ,['x1','y1','z'])
sage: R('x1+a')+S('x1+z')
a + 2*x1 + z
The following does not work:
sage: R=PolynomialRing(QQ,['a','x','y1'])
sage: S=PolynomialRing(QQ,['x1','y1','z'])
sage: R('x+a
Hi William, Thanks for your reply!
Something has turned up that I must attend to, so I cannot try your
solution at the moment. But I'll get back to it shortly.

Yes, and then
sage: a.n()
yields a Traceback,
