Change the default number of points in plotting
By default the plot function has only 200 points:
sage.plot.plot.plot(funcs, exclude=None, fillalpha=0.5, fillcolor='automatic', detect_poles=False, plot_points=200, thickness=1, adaptive_tolerance=0.01, rgbcolor=(0, 0, 1), adaptive_recursion=5, aspect_ratio='automatic', alpha=1, legend_label=None, fill=False, *args, **kwds)
But this look awful when plotting for example $f(x) = \frac{\sin x }{x}$. Since my machine is quite fast, I'd like to set the default to 50000 points.
Is this possible?
Perhaps you would also like to check out figsize options if you want to obtain a huge image (otherwise is there a reason to make plot_points greater then the x-resolution (in pixels) of the resulting image?)
