cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
Cos(120) = -0.5
cos(56)
Cos of 850 degrees?850 deg = 130 + 360*2 = 130 degBy the graph of the cosine: cos(130) = -cos(50)and cos(50) is not a fraction of a root.cos(50) = 0.6427876...Therefore, cos(850) = -0.6427876...
cos(32 deg) = 0.8480 approx.
-(sqrt3)/2
510 ~ (510-360) ~ 150 Cos 510 = Cos 150 = - Cos 30 = - ( radical 3 ) / 2

The statement of the problem is equivalent to sin x = - cos x. This is true for x = 135 degrees and x = -45 degrees, and also for (135 + 180n) degrees, where n is any integer.
Cos(x) equals zero at 90 degrees and 270 degrees. If x exceeds 360 degrees, cos(x) will equal zero at any increment of 90 + 180(n) degrees. In radians, this is equivalent to (pi/2) + pi(n) radians.
Cos 43
It is: cos(0) = 1
cos(125) = cos(180 - 55) = cos(180)*cos(55) + sin(180)*sin(55) = -cos(55) since cos(180) = -1, and sin(180) = 0 So A = 55 degrees.
cos 315 degrees is 4th quadrant same as cos (-45) degrees which is +0.7071
cos 34o ≈ 0.829 cos 34 = 0.86074
cos(25o) = 0.906307787 ==========
