Hello all,
first of I would like to thank you all for your hard work. SAGE is
amazing, and it only gets better.
It seems that I cannot find any documentation about setting up a public
(at least on our local department network ) sage server. I have set up
sage in a chroot environment, following t
There have been tons of great improvements to the plotting making
their way through trac lately. Do any of those changes for ranges
etc. deal with the very weird output one gets for e.g.
sage: plot((x-1)/(x+2),-4,4)
or, worse,
sage: plot(tan,-20,20)
In both cases, Sage isn't "recognizing" the

I couldn't find a double factorial function in sage. That is,
n!! == n*(n - 2)*(n - 4)...
Does Sage have a double factorial somewhere that I'm missing. If not,
could it?

There are indeed two things going on: the gp interpreter and the pari
library, You can use pari.set_real_precision() as you say.
I was mixing the two up. But in the example:

Hi,
sorry again for such a mail.
I know that there is a track about graphics disappearing from

There seems to be no /cells/n directory saved, so no images...too

Given that the first output has the right precision and the second doesn't,
it's surely a simple to fix caching issue.

This works :

Thanks. Is there any chance I could get a temporary login shell on

If you don't know how to do this, it would be easy for your sysadmin. That's
