How do the trigonometric functions work?

>>	Anonymous Tue May 20 12:32:20 2014 No.6544448 Is this another wild hotdog thread?

>>	Anonymous Tue May 20 12:42:18 2014 No.6544457 >>6544446 They don't. Rational trigonometry solves this problem. See here: http://web.maths.unsw.edu.au/~norman/papers/Chapter1.pdf

>>	Anonymous Tue May 20 13:52:40 2014 No.6544575 They're angles of the ratios of any two sides of a triangle, typically plotted as an inscription to a unit circle and expressed in radians or degrees. What else do you need to know?
