Geometry v. calculus
Dmitrii's calculus/analysis introduction of sine and cosine is interesting and definitely worth giving in this article. Yet, it seems to me that the standard geometric approach should be given as well, because CZ is an encyclopedia, where one expects to find world's standard knowledge presented as traditionally as possible. Therefore, unless I hear that there is strong disagreement, I will write a first introductory section with a few drawings illustrating the geometric definition and graphs of sine and cosine. Also the formula's for sin(α+β), and so on, are needed.
The definition of Pi (π), at the end of the article, is also interesting (and new to me), but would it not be better to move this to the article on Pi as one of the ways that Pi may be defined?--Paul Wormer 08:27, 1 November 2008 (UTC)
