NASA has a free, downloadable program called MathTrax (http://prime.jsc.nasa.gov/mathtrax/) that can plot the graph a user-specified, parameterized real-valued function of one real variable, or of an equation in two real variables. So far no big deal. But it also let's you "hear" the graph: as a vertical line sweeps across the display, the pitch rises as the graph rises and falls as the graph falls. You can also use various settings to hear when the value is positive vs. negative, or when the graph crosses the axes. It would be an interesting exercise to reproduce that MathTrax behavior in Mathematica. -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
