Identities for negative angles. Sine, tangent, cotangent, and cosecant are odd functions while cosine and secant are even functions. sin –t = –sin t. cos –t = cos t.

If they continue with their mathematical studies, they're sure to see it again in various contexts. där sin 2 v och cos 2 v är en förenklad notation för (sin v) 2 respektive (cos v) 2 som vi kommer att använda från och med nu. Det samband som vi just formulerat kallas den trigonometriska ettan . cos (2x) = cos 2 (x) - sin 2 (x) = 2 cos 2 (x) - 1 = 1 - 2 sin 2 (x) tan (2x) = 2 tan (x) / (1 - tan 2 (x)) sin 2 (x) = 1/2 - 1/2 cos (2x) cos 2 (x) = 1/2 + 1/2 cos (2x) sin x - sin y = 2 sin ( (x - y)/2 ) cos ( (x + y)/2 ) cos x - cos y = -2 sin ( (x-y)/2 ) sin ( (x + y)/2 ) Trig Table of Common Angles.

= (1 − sin2x) − sin2x. = 1 −sin2x − sin2x. = 1 − 2sin2x. = RHS. Therefore: cos2x − sin2x = 1 − 2sin2x.
