Learning about Conic Sections with Geometric Algebra and Cinderella
Proceedings of the Symposium Innovative Teaching of Mathematics with Geometric Algebra 2003 Nov. 20-22, 2003, RIMS, University of Kyoto, Japan.

Abstract: Over time an astonishing and sometimes confusing variety of descriptions of conic sections has been developed. This article will give a brief overview over some interesting descriptions, showing formulations in the three geometric algebras of Euclidean spaces, projective spaces, and the conformal model of Euclidean space. Systematic illustrations with Cinderella created Java applets are included. I think a combined geometric algebra & illustration approach can motivate students to explorative learning.
