Hi,
Ok, to solve, say, 253th order system of differential equations with
many functions one can simply write:
y=function('y',x)
y1=diff(y,x,1)
y2=diff(y1,x,2)
y3=diff(y2,x,3)
...
y253=diff(y252,x,253)
z=function('z',x)
z1=diff(z,x,1)
z2=diff(z1,x,2)
z3=diff(z2,x,3)
...
z253=diff(z252,x,253)
etc.

Dear Genaro,
Thanks for the interest in Sage!

Sorry, i'm new using Sage, i'm currently using the version 4.2.1. A
question I have, How can i save a file or worksheet to an .sage
extension file from the notebook?? I see that I only can save to .sws
file.
Another question is to use a .sage file, i need to define it with a
function with the def
I have to do it in my home directory. I have the two files -- tet-
latex 3.0-33.8.el5.ie386.rpm and tet-dvips 3.0-33.8.el5.ie386.rpm.
This for Centos 5.3. Now what do I do.

you can install tex in your home directory.
You would not need root permissions for this
(but make sure you have enough disk space - I imagine such providers
have disk quotas; a reasonable installation of tex can easily take
250Mb or so -- you get get away with much less, but this would require

Hi all,
I'm glad to inform you about release of OpenOpt 0.27 (numerical
optimization framework), FuncDesigner 0.17 (CAS with automatic
differentiation, convenient modelling of linear/nonlinear functions,
can use convenient modelling for some OpenOpt optimization problems
and systems of linear/nonli
I think that there are more options how to install things in Cents. If
yum is broken in your instalation, try some other method.
Do you have root ssh acces? If so, I think that easiest method is to
install texlive http://www.tug.org/texlive/
use wget ... to download, unpack and run install script
