Mark Cooper asks if there is a way to plot an equation of the form x^2 + y^2 + z^2 + xy + xz + yz == 1. KnoxPackages contains the commands PlotConicSection and PlotQuadricSurface that between them will plot any quadratic equation in two or three variables. KnoxPackages are available through MathSource (request 0204-512). KnoxPackages contain many commands useful for teaching precalculus, calculus, multivariable calculus, and linear algebra. Dennis M.
