Document Summary

This note is a generalization to notify each of the main trigonometric identities. 1 csc cos = sin(cid:16) . 1 sec tan = sin cos . 1 cot csc = sec(cid:16) . 1 sin sec = csc(cid:16) . 1 cos cot = cos sin . Cosine sin (2 ) = 2 sin cos cos (2 ) = cos2 sin2 cos (2 ) = 2 cos2 1 cos (2 ) = 1 2sin2 . 2 sin cos sec (2 ) = 1 cos2 sin2 sec (2 ) = sec (2 ) = Sine sin (a) sin ( ) sin (a) sin ( ) = [cos ( ) cos ( + )] = cos ( ) cos ( + ) 2 sin (a) cos ( ) sin (a) cos ( ) = Cosine cos (a) sin ( ) cos (a) sin ( ) = cos (a) cos ( ) cos (a) cos ( ) =
