With the advent of the new coercion model, did we get the incredibly
cool possibility of adding canonical coercions locally, as promissed
at SD7? I'd love to be able to type something like:
K.=Numberfield(x^2-2)
E=EllipticCurve([0,0,r2,0,0]

Hardly, considering that this is what Python itself does:
>>> 1+1j > 1-1j
Traceback (most recent call last):
File "", line 1
I understand that Python really likes things to be comparable with
"<", but from a mathematical point of view the following makes me
cringe:
sage: C.=ComplexField()
sage: 1+i > 1-i
True
sage: 1+i < 1-i
False

Hello all,
While we continue to add tests to the notebook code, there are some
things that we just can't test directly in Python such as browser
interactions / Javascript / etc. Luckily, there is a nice software
package designed to handle this problem: Selenium

hi,
when one uses plot_points and plot_division in a plot command, there
is something misleading (imho) :
plot_points = 3 gives exactely 3 points in the initial plot (before refinement)
plot_division = 5 can add up to 6 points to the original 3
It is not obvious also that this number of subdivi

Hi group,
i'am a little bit confused while analysing Sage Python packages and
(newbie's default) a would like to ask a simple question :
when one types
var('x')
f_exp = exp(x)
plot_f_exp = plot(f_exp)
plot_f_exp.show()
what happens exactly in the "plot()" part ?
is sage/plot/plot.py in charge o

Hi group,
At the URL:

the following sentences sound funny to me:

Should [1] read: "You can get the complete source for Sage to compile under

Hi,
I am interested in modifying the way Sage draws Graphs and,
especially, multi-edged graphs.
Emily Kirkman seems to be working on that point but her blog doesn't
give any information on recent success.
I also want to use Matplotlib to draw graphs. Should i start from
scratch or try to contact
