Talk:Trigonometry

Actually, sine, cosine, and tangent are the reciprocals of cosecant, secant (not sick ant), and cotangent. Inverses is where you switch the x's and y's. The inverse of sine is arcsin or sin^-1.Coffsneeze 17:57, 31 March 2007 (UTC)[reply]

Complex?[change source]

This article has very complex English! I have doubts about whether "It has some connection to geometry, although there is disagreement on exactly what that connection is; for some, trigonometry is just a section of geometry." has any significance at all to this article.

Also, it is not called a "right triangle", it is called a "right-angle(d) triangle", isn't it? Adamd1008 (talk) 20:20, 14 June 2008 (UTC)[reply]
