Hi folks,
Quite a few people at Sage Days 14 are fans of emacs and therefore trying to
use sage-mode. In particular, Mike Stillman had two questions that I didn't
know how to answer. It might be that these are not implemented as of yet
and should be, in which case I'll make enhancement trac tick

Hi everyone,
I am trying to apply a patch. I downloaded the actual patch (not the
html file) to /tmp

from the sage prompt.
Both calls result in various (insignificant) warnings and an error:

I would like to determine the Galois group of x^12 + 2x +2 over Q. I
don't know how to read the answer I got from Sage:

Calling sage-spkg on database_gap-4.4.9
You must set the SAGE_ROOT environment variable or
run this script from t
Do you mean
sage: t = var("t")
sage: numerical_integral(abs(sin(t^2)),0,3)

Why can't do integrate( abs( sin(t^2) ), t, 0, 3) ?
Sage just returns the question...

Sage prefers methods to properties:

cos(1)
Using
z = exp(I*r*cos(theta)).real()
makes your parametric_plot3d work, too.

To actually do some coding it would be nice to have some sort of IDE
on my ubuntu machine. So I first gave emacs sage-mode a try, installed
it according to wiki (http://wiki.sagemath.org/sage-mode) using the
output form the install script to set up ~/.emacs.
Code Highlighting works.. but Ctrl-c C
Thank you very much, for the useful information !
Where can I find a complete and good documentation about Sage, better
then the tutorial or the reference ?
Thank you again.
