cos(30 deg) = sqrt(3)/2 = 0.8660 approx.
The cosine of 8 degrees is 0.99026806874157031508377486734485
Cosine is 0.766
The cosine of 24 degrees is 0.913
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).
cosine(59 degrees) = 0.51504 (rounded)
Cos(30) = sqrt(3)/2 = 0.866025403.... ( Which is irrational).
cos(30) = sqrt(3)/2 so cosine squared is 3/4.
0.866 ( or (sqrt 3)/2 )
The cosine of 8 degrees is 0.99026806874157031508377486734485
Cosine is 0.995
Cosine is 0.766
The cosine of 150 degrees is equivalent to the cosine of 180 degrees minus 30 degrees, which can be expressed as (-\cos(30^\circ)). Since (\cos(30^\circ) = \frac{\sqrt{3}}{2}), it follows that (\cos(150^\circ) = -\frac{\sqrt{3}}{2}). Therefore, (\cos 150^\circ = -\frac{\sqrt{3}}{2}).
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.

First make sure your calculator is in 'Degree Mode (D)'. Then using the 'Inverse' of 'Sin' , shown as 'ArcSin' or ' Sin^(-1)' . enter '0.5', followed by '=' . The answer should be '30' ( 30 degrees).
