Edwards, Jr., 1979, Chapter 2, Archimedes used inscribed and circumscribed polygons to get a very tight bound on the value of pi.

Should it convince you? Note that my lack of thinking to do that lead to this post and some interesting ways to approx pi, ln(2),<br />pi-2ln(2) and pi+2ln(2).GASARCHhttps://www.blogger.com/profile/03615736448441925334noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-58661930903321979242019-07-01T10:58:53.826-05:002019-07-01T10:58:53.826-05:00I'd avoid W Alpha or W Beta.
