This unit consists of two computer programs. The first teaches X,Y plotting; the second is a demonstration of coordinate transformations, matrices, vector equations of lines and perspective and will draw a picture of any...

A discussion of the history of conic sections, one of the oldest math subjects studied systematically and thoroughly, with a description, formulas, properties, a proof, Mathematica notebooks, the ellipse seen as a...

Through the ages, various forms of visual expression have implicitly (and explicitly) drawn on a variety of mathematical principles. The people at the Center for Cultural Design at Rensselaer Polytechnic Institute are...

A discussion of the many ways to classify curves, how they are named, a curve family tree, and interconnection between curves, with related Web sites about fractals and curves. Hosted by the Math Forum.

This lesson from Illuminations explores conic shapes. The shapes circle, ellipse, hyperbola, and parabola are illustrated. Students will discover how to cut a double-napped cone to create the various conic sections. The...
