Formula for radius

edit

The formula for the smaller circle is not r-1. it is 1-r --[ unsigned comment ]

Fixed. --Jorge Stolfi (talk) 02:15, 9 October 2014 (UTC)Reply

Removed "Centers" section

edit

I deleted the Centers section since it was a very incomplete (and thus incomprehensible) copy of the paragraph "The positions of the circles can be found using the triangles shown above [ ... ] " from Wolfram MathWorld's article. --Jorge Stolfi (talk) 02:15, 9 October 2014 (UTC)Reply

Rename article?

edit

The article should perhaps be renamed "Archimedean circles of the arbelos". I would think that "Archimedean" is better English than "Archimedes'" (or "Archimedes's" as the manuals of style recommend). It seems safer to specify "of the arbelos" (1) in case there are other "circles of Archimedes" in other contexts, (2) so that the title can be understood without reading the article, (3) since they are mentioned in only one of his propositions. @Jorge Stolfi:

I agree with Jorge. This article must be renamed, as Book of Lemmas is accepted to not be authored by Archimedes. 174.3.155.181 (talk) 01:03, 11 June 2016 (UTC)Reply
