Hi there!
When trying to plot the probability density function of a skew
normal-distribution as a function of an alpha skewness I found the
following error:
sage: from scipy.stats import norm
sage: var('alpha')
sage: skew_norm(x, alpha) = 2*norm.pdf(x)*norm.cmd(x*alpha)
TypeError:
My knowledge of the French language being next to nothing, I don't
know where within the Sage website to link to your document. On the
other hand, this page [2] links to documents such as reference cards
(cheat sheets), screencasts, tutorials, blogs, etc. Do you think your
document could be
I just thought I'd try this question one more time:

Today I was reading the wikipedia entry for sage (http://
en.wikipedia.org/wiki/Sage_%28mathematics_software%29), and decided to
try the first example :
sage: show(solve(a*x^2 + b*x +c == 0, x ) [0])

Wikipedia proposes to write this :
x,a,b,c =
That certainly solves the problem. From the wikipedia entry, it's not
really clear that this needs to be done. Or is it just me?

Sage complex numbers already print out that

Not in a user friendly way. The complex I is just a number field
element and number fields don't support latex output with different

Hi Sagers,
Could someone tell me how to solve this system of PDEs symbolically:
du/dx + dv/dy = A
au - bv + c(dt/dx) = 0
bu + av + c(dt/dy) = 0
a,b,c,A are constants.
I am looking for a general way of symbolically solving a set of PDEs,
i mean the functions that may be used.
Thanks.

No module named _tkagg
Would anybody tell me how to install this module in the Python version
of Sage. I am
