The identities of cosine 67° are as follows:
cos67°
= sin (90°+67°) = sin 157°
= sin (90°-67°) = sin 23°
-cos67°
= cos (180°+67°) = cos 247°
= cos (180°-67°) = cos 113°
Note that cos67° is periodic: cos (67° + n × 360°) = cos 67 degrees, n.
There are more formulas for the double angle (2 × 67°), half angle ((67/2)°) as well as the sum, difference and products of two angles such as 67° and β.

What is cos 67°?
In a triangle which has one angle of 90 degrees, the cosine of the angle of 67° is the ratio of the length of the adjacent side a to the length of the hypotenuse h: cos 67° = a/h.
In a circle with the radius r, the horizontal axis x, and the vertical axis y, 67 degrees is the angle formed by the two sides x and r; r moving counterclockwise is the positive angle.
As detailed in the unit-circle definition on our homepage, assumed r = 1, in the intersection of the point (x,y) and the circle, x = cos 67°.
Bringing together the triangle definition and the unit circle definition of cosine 67 degrees, a = x and h = r = 1. It follows that
