Document Summary

Assume can be any angle. y (x, y) y x. 1 x sin = cos = tan = y. 1 y x csc = sec = cot = Domains of the trig functions sin , cos , tan , 2(cid:17) , where n z csc , sec , cot , 6= n , where n z. Tan csc 1 and csc 1 sec 1 and sec 1. The period of a function is the number, t, such that f ( +t ) = f ( ) . So, if is a xed number and is any angle we have the following periods. sin( ) t = cos( ) t = tan( ) t = 2 csc( ) t = sec( ) t = cot( ) t = Half angle formulas tan = sin cos cot = cos sin . Reciprocal identities sin = cos = tan = 1 cot csc = sec = cot =
