Cos 30: We will discuss what are different

We will discuss what are different ... 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. Learn how to derive the value of cos 30 degrees using trigonometry formulas and tables. The value of cos 30 degrees is √3/2, which is also the value of sin 60 degrees. 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 ...
