Weirdly enough, I'm not sure if this is so important, after all. It might be
cleaner to just define a more basic Class, which takes expressions as
attributes.
Doing arithmetic on these objects might get a little weird, but I'm sure the
purpose of the object and the context of its creation will

[var('{0}'.format(variable)) for variable in

self.exp = expression

self.attr[option] = attributes(option)

Hi everyone,
I noticed that a thread was developed for this sort of thing (http://
groups.google.com/group/sage-support/browse_thread/thread/
d50dc3bc2bdbeab0/34798c0585fc034f?lnk=gst&q=nicolas&fwc=1#), but I'm a
newbie, and a lot of it went over my head.
Is there a simple to create a subclass of
Hi,
I've been googling around to find a way to set up pydev and sage, and
have had nothing but the worst of luck.
sage 4.7 is located in /home/steven/sage-4.7, and I've created a
"sage_python" python interpreter who's location is "/home/steven/
sage-4.7/local/bin/python".
I've set the following
So, for anyone interested, I was able to *sort-of* solve the Gegenbauer
polynomial problem.
Using a lambda-function:
C = lambda (n, Lambda, x): sum(
[(2*x)^(n-2*m)*(-1)^(m)*rising_factorial(Lambda,n-m)/(factorial(m)*factorial(n-2*m))
for m in [0..floor(n/2)]] )

Thanks. I might work on some sort of script, I suppose, because maple has an
"intersectplot" function, and that's definitely something I need for this
project.
How hard would it be to scan through the list of solutions to
"solve([nodalSet1,nodalSet2], [x,y,z], dict_solution=True)" and use

Thanks for the reply. In my particular instance, there are a lot of
constants, and the problem looks a bit difficult to automate. Here are
the specifics:
var('x1,x2,x3,x4,k,x,y,z', domain=RR)
# Definition of P = Im[(x1 + i x2)^k]
P(k, x1, x2, x3, x4) = (x1^2 + x2^2)^(k/2)*sin(k*arctan2(x2,x1))

Hi,
I know that sage has ultraspherical(n,a,x) implemented, however if a
is not a number, ultraspherical(n,a,x) returns the error:
NameError: name 'a' not defined
(even if I write a = var('a')). This, partly, flies in the face of the
fact that the Gegenbauer polynomials are functions of a.

Hi everyone,
I'm new to SAGE, so I'm sorry if this is an amateur question, however
I've been trying to find the simplest way to plot the intersection of
two surfaces. The impression I'm under is that I "should" be able to
do this with implicit_plot3d and solve. More specifically, I have two
