#5706: implicit_plot totally sucks when input an equation
----------------------+-----------------------------------------------------
Reporter: was | Owner: was
Type: defect | Status: new
Priority: major | Milestone: sage-3.4.1
Component: graphics | Keywords:
----------------------+-----------------------------------------------------
Make Sage hurt:
{{{
var('x,y')
implicit_plot(x^2+y^2 == 1, (x,-2,2), (y,-2,2))
}}}
The problem is that implicit_plot takes a function, not a symbolic
equation, so it views "x^2+y^2 == 1" as a function --- and that is very
painful.
SOLUTION: Check if the input is an equation, and if so, make RHS zero, and
plot corresponding function equal to 0.
