Sage Support:
I am a new Sage user and I have a question regarding the plot function
in Notebook.
Below is a little snippet of code I wrote to plot the Bessel_J
function for various nu on different intervals. The snippet below is
just an exercise in learning python and its plot function.

Is there a way to compute coefficients of half-integral-weight modular
forms in Sage?
Specifically I want the coefficients of the weight 5/2 form on Gamma_0
(4*13) that is in Shimura-Kohnen correspondence with the weight 4
newform (of degree 1) on Gamma_0(13).
The first few coefficients of the w

I didn't use that because I woke up a few minutes ago and I'm still groggy. :-)

Hi,
Having several Jmol plots in a worksheet often leads to problem for
me. For example, the following procedure consistently gives failure:
1. Open a new worksheet.
2. Create two cells with content "sphere()" and evaluate them. Two

3. Save and quit the worksheet.

I was recently experimenting with iterators over permutations, and
using them to find if a graph was Hamiltonian. This was done by brute
force - no clever tricks - simply by trying every possible permutation
of vertices and seeing if each was a cycle.
Now there seem to be (at least) two ways of
