can be "translated" in terms of x and y, so:

[tex]x = \sqrt{\frac{\sqrt{u^2+v^2}+u}{2}}[/tex]

[tex]y = \sqrt{\frac{\sqrt{u^2+v^2}-u}{2}}[/tex]

Exist another form more simplified of write x and y in terms of u and v? I tried rewrite these expressions using the fórmulas of half angle but didn't worked...
