Hello all... I'm working on some Mathematica for a Calc IV course and needed some help with quadric surfaces. How can you get Mathematicatica to graph a nice looking hyperbolic paraboloid as well as other quadric surfaces like you see in the textbooks. I've ended up using ParametricPlot3D, CylindricalPlot, and others but I still can't get a perfect/textbook example of a hyperbolic paraboloid. Help??
