It's astounding! (It's also pretty difficult, and you'll probably want to be able to have time to "follow along" on your own paper.) I liked this website, which has step by step diagrams to go with the text. http://web.calstatela.edu/faculty/hmendel/Ancient%20Mathematics/Archimedes/QuadraturaParabolae/QP.contents.htmlEvelynhttps://www.blogger.com/profile/08903667625039887922noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-1259324803634480912016-01-02T17:09:56.107-08:002016-01-02T17:09:56.107-08:00The circumscribed looks lots harder to figure out....The circumscribed looks lots harder to figure out.

We discovered that it converges very very slowly. (but I think it's still a bit faster than the arctan taylor series.)Haohttps://www.blogger.com/profile/02348974241652264510noreply@blogger.com
