The value of angle boa in the given right triangle is pi/6 and the given ratio as per the definition of cosine ratio represents the value of cos 30 degrees cos 30° =length of. Cos 30 degrees is written as cos 30° and has a value in fraction form as √3/2. √3/2 is the value of cos 30° which is a trigonometric ratio or trigonometric function of a particular angle.
Find the value of cos 30 geometrically get the answers you need, now! ⚆ᴥ⚆ the value of cos (30°) is √3/2 or approximately 0.8660254037844387. The value of cosine 30 degrees is √3/2, which is approximately 0.866.
Therefore, the exact value of cos 30 degrees is written as 0.8660 approx. To understand how we get. The reference angle for 330° is calculated as follows: Cos 30° = √3/2 is an irrational number and equals to 0.8660254037 (decimal form).
To find the value of cos (330°) without a calculator, we can use the unit circle and the fact that cosine is a periodic function with a period of 360°. √3/2 is the value of. The value of angle boa in the given right triangle is pi/6 and the given ratio as per the definition of cosine ratio represents the value of cos 30 degrees cos 30° =length of. Therefore, the exact value of cos 30 degrees is written as 0.8660 approx.
