do I need to know in order to download Sage? What is it that everyone
thinks I already know that in fact I do not know?

at I want to do is not to bound but to clip the plot to a
specific (3D) window, smaller than the entire plot.

For exemple:

Hi,
I asked this question 3 days ago, but got no answer. This problem
hinder me in my project. I would appreciate an answer, even if what I
want to do is impossible.

Is there a way to do that?

By the way, .save() for parametric_plot3d does not work neither in a
konsole nor in the notebook, but the examples online of .save() do not
work in the notebook while they do in a konsole.

Is there something I misunderstand?
Anyway, may-you sugest a workarround?

p.s. It fails also with sqrt(norm(z)).
example:
sage:z.rayon()
0.333
sage:z.rayon
abs((1.414213562373095*(1.414213562373095*I + 1) +
1.00*I

Well I did it this morning. This is what I was triing to do:

He, I don't even understand what is a parametric plot (and what I
found in SAGE literature is to complex for me). Can you

Wow that answer was fast,
Well if there a way to name it without drawing it (because I need to
put it in an if and I don't want it to by show any

Hi,
(I am a Newbie)
I need to count complex number in Tuples and the only way I found out
is to use Tuples(l,1).count() or UnorderedTuples(l,1).count() (I don't
understand the difference), but I have two problems.
First, it counts only once an element that is twice in my Tuples.
ex: sage:
20 matches
