Subject: Re: Conic sections
Brad, A couple of suggestions. First, if I were trying this, I think I would control the distance to the vertices and the foci by sliders, and then compute the eccentricity from these so that as the shape changed, they would see that the eccentricity moved in relation. This might require a separate sketch for hyperbola and ellipse. Suggestion two... There is a dynamic geometry discussion group and the guys there are masters of working with these kinds of problems. Most of the Key Curriculum Press guys monitor this list, so send them your question. Usually what you get back are sample files. The URL for the discussion page is at http://mathforum.org/discussions/ . The dynamic geometry discussion list is toward the bottom left. Good luck -Pat Ballew, for the T2T service Thanks for visiting our on-line community. Visit Teacher2Teacher again at http://mathforum.org/t2t/
