For convenience, we choose each side to be length 2. When you bisect an angle, you get 30 degrees and the side opposite is 1/2 of 2, which gives you 1. Using that right triangle, you get exact answers for sine of 30°, and sin 60° which are 1/2 and the square root of 3 over 2 respectively. Exact values of sin(30), cos(30), tan(30), csc(30), sec(30), cot(30), Find exact values of all trigonometric functions when the angle is 30 degrees,blackpenr Question: Question 4 Solve The Problem. Given Cos 30º = V3 2. Use Trigonometric Identities To Find The Exact Value Of Sin 2 30°. Nw 0 1 In Sexagesimal angle measuring system, the cosine of angle 30 degrees is written as cos.

1 Answer sankarankalyanam The value of Cos 30 degree is √3/2 Another Different form of Cos 30° is cos pi/6 or cos π/6 Hence, cos pi/6 = √3/2 Cos 30° = √3/2 is an irrational number and it equals 0.8660254037 approx. And then, 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 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.

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 Se hela listan på gigacalculator.com When we find sin cos and tan values for a triangle, we usually consider these angles: 0°, 30°, 45°, 60° and 90°. It is easy to memorise the values for these certain angles. The trigonometric values are about the knowledge of standard angles for a given triangle as per the trigonometric ratios (sine, cosine, tangent, cotangent, secant and cosecant). Give exact values for \cos 30^{\circ}, \sin 30^{\circ}, \cos 60^{\circ}, \sin 60^{\circ}, \cos 90^{8} and \sin 90^{\circ} 2021-02-05 · Solution for 2. Find the exact value of cos 30°.
