( 30 °). The value of cos of angle 30 degrees is equal to 3 2 in fraction form exactly. It is an irrational number and equals to 0.8660254037 … in decimal form and the same value is considered as 0.866 approximately in mathematics. 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.

How do you find the exact value of #cos(-30)#? Trigonometry Right Triangles Trigonometric Functions of Any Angle. 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. 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.

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. Exact Trigonometric Function Values What angles have an exact expression for their sines, cosines and tangents? You might know that cos(60°)=1/2 and sin(60°)=√3/2 as well as tan(45°)=1, but are 30, 45 and 60 the only angles up to 90° with a formula for their trig values? 2008-08-29 · the exact value is cos(75°).
