I think many people--teachers in particular--are interested to use Mathematica to generate graphics that illustrate conic sections. I have completed writing a few Mathematica programs that does this. The program will generates graphics of a double cone and slicing plane of arbitrary angles, together with their intersections and Dandelin spheres. You may get these Mathematica programs along with examples of their graphics at my web page http://www.best.com/~xah/SpecialPlaneCurves_dir/ConicSections_dir/conicSections.html Xah xah at best.com; 74631.731 at compuserve.com http://www.best.com/~xah/PageTwo_dir/more.html Mountain View, CA, USA ==== [MESSAGE SEPARATOR] ====
