I was just messing around with implicit_plot and attempted the
following, which is directly from the docstring:
sage: x,y = var('x,y')
sage: f(x,y) = x^2 + y^2 - 2
sage: implicit_plot(f, (-3, 3), (-3,
3),fill=True).show(aspect_ratio=1)
However, I don't think this results in the intended plot (i.e
Hullo,
The most recent version I have of Sage (3.1.4) believes that I want my
implicit plots filled. For example,
implicit_plot(x^2+y^2-1,(x,-5,5),(y,-5,5))
gives a filled-in disc, not an open circle.
This happens with open curves, too; check out
implicit_plot(5*x^4-x^2-y^2,(x,-5,5),(y,-
