# How to draw a cone in Sage?

Given a cone with equation

z^2 = x^2 + y^2,

how would I draw it in Sage?

I tried turning it into a function and passing arguments but it didn't work out for me.

Try to give a look to the Sage's Reference Manual precisely here:sagemath.org/doc/reference/sage/plot/plot3d/… – Giuseppe May 21 '12 at 16:54
