Various Curves

I draw curves represented by parametric equations or polar equations using Cinderella. Starting with those found in high school Mathematics III textbooks, I draw curves introduced in the "Encyclopedia of Curves" (edited by Masami Isoda and Maria G. Bartolini Bussi, Kyoritsu Shuppan) by imitating drawing instruments.

Those drawing instruments are posted in the "Mathematical Machine Laboratory - Japanese Version" on this page.

The following are articles drawn using Cinderella.
