√3/2 is the value of Cos 30° which is a trigonometric function of a particular angle. 2019-02-27 · What is value of sin 30?What about cos 0?and sin 0?How do we remember them?Let's learn how. We will discuss what are different values ofsin, cos, tan, cosec, sec, cotat0, 30, 45, 60 and 90 degreesand how to memorise them.So, we have to fill this tableHow to find the values?To learn the table, we sho I have noticed that students cannot actually remember values of six trigonometric ratios (sin, cos, tan, cosec, sec and cot) for 0, 30, 45, 60 and 90. These values are used very often and it is recommended from my point of view that student should be able to tell the values instantly when asked.

It is essential to find it in order to find the $\cos{\Big(\dfrac{\pi}{6}\Big)}$ value.

The exact value of $\cos{(30^°)}$ is evaluated theoretically on the basis of this property. The lengths of opposite side and hypotenuse are known but the length of adjacent side is unknown in this case. It is essential to find it in order to find the $\cos{\Big(\dfrac{\pi}{6}\Big)}$ value.

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. The value of cos 30 is equal to the value of sin 60 since they complement each other within a triangle.

2sin 30. 2. 1.

Tan 30 = sin30/cos30 Sin30 = 1/2 , cos30= √3/2 So tan30 =sin30/cos30 = (1/2) ÷(√3/2) =1/√3 So Ans will be 1/√3 All the best and upvote if it's helpful
