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$'], contours = [0.1, 0.2, 0.3, 0.5, 0.7, 1.0, 2.0, 4.0],
fill=False, legend_label='qwall');
This is the error message that I get when processing the code:
The error I get is: File "<ipython console>", line 1 SyntaxError:
keyword argument repeated (<ipython console>, line 1).
Does it have something to do with assigning the variables?
