Hi, I've spent 4 days to try to use ImplicitPlot on an equation, without success: The Equation I try to plot has 2 nested square roots, ans 2 variables : something like Sqrt[2*Sqrt[2X^2 -Y^2] - 2*Y +X^2]==0 (it's not exactly this one: it's just to give you an idea ) Of course this equation is not defined everywhere, and the domain where it's defined is complex. When i try to "ImplicitPlot" this equation, i've an answer : "The contour is attempting to traverse a cell in which some of the points have not evaluated to numbers, and it will be dropped" followed by "Further output of ContourGraphics::"ctpnt" will be suppressed during this calculation." So i don't have any answers ( and there are answers of course :) Is there some options or another solution to draw this implicit equation ?
