You'll need to type the whole part after
def f(y,t):
in just one line, and similarly for the whole plot command. Google
groups tends to cut off things at a fairly short line length.

I still get an error:

Hi,
I am having issues with plotting contour plots for bessel functions.
Here is one of the lines of codes for a plot:
Sage: y,t = var('y,t')
Sage: contour_plot(lambda y,t: (sqrt(t^2+y^2)/(2*pi*y))*(bessel_J(0,
t ).arccos()), (t, 0, 3), (y, 0, 4), fill = false, axes_labels=['$gro
$','$kro$'], con
Dear sage expert
Thank you a lot for the excellent work on sage !
I have the following problem:
On Mac OS X 10.5, using rpy2 fails, the library
libintl.3.dylib
could not be loaded, see below.
Is there anything I can do to resolve the problem?
Thanks,
Silvio

Dear sage-support,
Is there a possibility ti visualize a Picture in the notebook ?
For example: we read a .png image, and we would like to modify it, treat
it and so on (we know how to to this with sage); at the end visualize
the result in the notebook (we do not know how to do this...).

Every element in the 9x9 determinant is a polynomial in some variable
x with integer coefficients. Doing print m.parent() gives

Does anyone know how to enlarge the memory limits set by sage?
I get the following message when running a certain computation that
involves computing large determinants.
Memory limit reached. Please jump to an outer pointer, quit program
and enlarge the
memory limits before executing the program
