Hi,

I am trying to plot the following function in 3 variables {z,w,l}:

Plot3D[((1+l)^2+2*w*(w-l)-(l+1)*sqrt((l+1)^2+8*w*(w-l)))/(2*(l-w)*((l
+1)^2-w*(w-l)))-1+(-x+sqrt((x+(w-l)*x^2)/w))*(1-x*(l-w)-w*sqrt((x+(w-
l)*x^2)/w))/(sqrt((x+(w-l)*x^2)/w))=0, {w,0,1}, {l,0,1}, PlotRange-
>{0,1/2}]

The outcome in Mathematica is that x=0 constant, while from numerical
methods, excel and intuition due to the functional form I find a one?
sheeted hyperboloid.

Any suggestion? Maybe I am writing the wrong command to plot it.

Cheers,

Marco
