Hi;
I am trying to graph/plot a 3D object that is created when you rotate y = 1/z, about the z-axes, obtaining the surface of revolution x^2 + y^2 = (1/z)^2. The object looks like a cone with a large base starting on the x and y coordinate plane at -2 to 2. The cylinder gets smaller as it moves up the z-axes (with the z-axes in the center of the cylinder) and ends around z = 4 with the diameter of the cone at the top around 1.
Thanks,
Mitch Sandlin
