Talk:Trigonometry/Geometric Definitions of Trig Functions

The unit circle in question by definition has a radius equal to 1. Then the March 20, 2004 definitions of sin, cos, and tan by Jedwards are correct. User 211.29.136.11 apparently thought that the radius was not specified and set it equal to b, and accordingly divided x and y in the sin and cos definitions by b. I explained that the unit circle has a radius of 1 by definition, and added a link to the previous section on the unit circle. The unit circle section is very short and I think I will combine these two sections into one maybe sometime in the future. H Padleckas 22:25, 29 May 2004 (UTC)
