My students study parametric and polar equations in Advanced Placement Calculus
BC. I use the Ostebee/Zorn text, and when introducing parametric equations the
authors say "Parametric curves come in mindboggling variety. ... beauiful,
useful, interesting, or all three." At this point I lead my students to the
above site. I expect them to become familiar with some standard curves such as
the ellipse and Folium of Descartes, but almost all the students investigate far
more than the required few.
Links to numerous such curve applets can be found on the JavaSketchpad home page
http://www.keypress.com/sketchpad/java_gsp/index.html ; for example, the awsome
collection at
http://math2.math.nthu.edu.tw/jcchuan/javasketchpad/jsp.html
I put these URL on my course web page.
These illustrations open up a whole new world of mathematics potential for my
students
