We know that cos (a-b) = cos a * cos b + sin a sin b cos 15 = cos (45–30) => cos 15 = cos 45 cos 30 + sin 45 * sin 30 => cos 15 = (1/√2)* (√3/2) + (1/√2

( 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. sin(60 degrees) = cos(30 degrees) cos(60 degrees) = sin(30 degrees) We will not do this computation, but if we replace 30 degrees with 20 degrees and 60 degrees with 70 degrees, you will find a similar result. What is {eq}\cos 30° {/eq} in the simplest radical form? Trigonometric function A function of form f(x)=sinx, cosx, tanx etc are called the trigonometric function.

Cos 30 deg

In geometric terms, the cosine of an angle returns the ratio of a right triangle's adjacent side over its hypotenuse. For example, the cosine of PI ()/6 radians (30°) returns the ratio 0.866. = COS(PI() / 6) // Returns 0.886. 2007-06-03 Cos(30) = 0.866025403784 This is the same answer you will get if you have a scientific calculator set to DEG mode and then enter 30 followed by the Cos button.

Cos is the cosine function, which is one of the basic functions encountered in trigonometry. It is defined for real numbers by letting be a radian angle measured counterclockwise from the axis along the circumference of the unit circle. Cos [x] then gives the horizontal coordinate of the arc endpoint. The equivalent schoolbook definition of the cosine of an angle in a right triangle is the
