0.866 ( or (sqrt 3)/2 )
The cosine of 60 degrees is 0.5
-- If the "14" is degrees, then the cosine is 0.970 . -- If the "14" is radians, then the cosine is 0.137 . -- If the "14" is grads, then the cosine is 0.976 .
cosine(28 degrees) = 0.88295 (rounded) cosine(28 radians) = -0.96261 (rounded)
Cosine of 90 degrees is zero.
0.8192
Cos(30) = sqrt(3)/2 = 0.866025403.... ( Which is irrational).
cos(30) = sqrt(3)/2 so cosine squared is 3/4.
cos(30 deg) = sqrt(3)/2 = 0.8660 approx.
The cosine of 90 degrees is zero.
The cosine of 8 degrees is 0.99026806874157031508377486734485
Cosine is 0.995
Cosine is 0.766
The cosine of 60 degrees is 0.5
The cosine of 24 degrees is 0.913
The value of cos 30 degrees is (\frac{\sqrt{3}}{2}). This is a commonly used value in trigonometry, derived from the properties of a 30-60-90 triangle. In this triangle, the ratio of the adjacent side to the hypotenuse corresponds to the cosine of 30 degrees.
To find the cosine of a specific angle, you can use a scientific calculator or refer to the unit circle. For example, the cosine of 0 degrees (or 0 radians) is 1, while the cosine of 90 degrees (or π/2 radians) is 0. Additionally, you can use trigonometric identities or tables for common angles such as 30 degrees (√3/2), 45 degrees (√2/2), and 60 degrees (1/2).
