Answer:
In trigonometry, the cosine function is defined as the ratio of the adjacent side to the hypotenuse. If the angle of a right triangle is equal to 30 degrees, and then the value of cosine at this angle i.e., the value of Cos 30 degree is in a fraction form as √3/2. It is noted that the value of Sec 30 will be reciprocal of Cos 30 value.
Cos 30 Value
Cos 30 degrees is written as cos 30° and has a value in fraction form as √3/2.
Cos 30° = √3/2
Cos 30° = √3/2 is an irrational number and equals to 0.8660254037 (decimal form).
Therefore, the exact value of cos 30 degrees is written as 0.8660 approx.
√3/2 is the value of Cos 30° which is a trigonometric ratio or trigonometric function of a particular angle.
Cos 30
Another alternative form of Cos 30° is pi/6 or π/6 or Cos 33 (⅓)g
