The result can be shown in multiple forms. Exact Form: Cos 30 degrees is written as cos 30° and has a value in fraction form as √3/2. Cos 30° = Representing Cos 30°: When the ratio of the base of the reference angle with the hypotenuse is taken, it gives us the cosine value of the ratio at that specific angle. When this angle is of 30°, then the value is called cos 30.
