Hello, with plot_vector_field I can draw the vectors of a given field.
However, how can I plot field lines? I.e. the curves that have the
vectors show by plot_vector_field as tangents.
If there is not a built-in function, any idea on writing one ad-hoc?
kind regards,
renato

Hi, this seems very basic, but I wasn't able to figure it out. Let's say
I have a function:
sage: f(t)
-4*(5*sqrt(2)*cos(1/2*sqrt(2)*sqrt(5)) -
2*sqrt(5)*sin(1/2*sqrt(2)*sqrt(5)))*sin(1/2*sqrt(5)*t)/(sqrt(5)*sin(1/2*sqrt(2)*sqrt(5))^2
+ sqrt(5)*cos(1/2*sqrt(2)*sqrt(5))^2) +
Hi,
I am aware that there is a lot of information available on the topic
however as some of it is few years old, I just wanted to be sure I
missed nothing.
I wonder what is currently the easiest way to make an interactive
3d plot from numerical data inside sage notebook? Something like
plot3d
Sorry for my premature posting. I deleted the posting as soon as I
found that reinstalling Sage from scratch brought everything back to
normal. The application must have gotten corrupted, not the notebook.
Thanks anyway for the advice.

Is it ok to try to revive this posting?
It would be a great help to me if fast_float() could be gotten to work
on large polynomials (60,000 terms).
I suppose that fast_float() makes a space-time tradeoff that might be
insurmountable. Still, the fact that fast_float(p) kills the
worksheet
Hi,
Thanks for the patch to fix simple API !I have tested the patch
in sage 4.5.1.

Definitely!
I slightly modified your example:
First cell:
{{{
R.x = QQ[]
Nterms = 6
}}}
Second cell:
{{{
p=0
for k in range(Nterms):
p += x^k
p in RQ
}}}

that the evaluation of the for-loop is finished, while in fact the

Hi all,
This is a sequel of my former question:
http://groups.google.com/group/sage-support/browse_thread/thread/ed74c71c01cb9f26/63a88bb12708c275?lnk=gstq=fractional+ideal#63a88bb12708c275
I use SAGE 4.4.alpha0 (with Virtual Machine) and the online SAGE.
Note that the former contains PARI/GP
