cos (30°) = √3/2 In the fraction format, the value of cos (30°) is equal to √3/2. The cos of 30 degrees is √(3)/2, the same as cos of 30 degrees in radians. To obtain 30 degrees in radian multiply 30° by $\pi$ / 180° = 1/6 $\pi$. Cos 30degrees = cos (1/6 × $\pi)$.

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.

Matemātika 9.klasei/Ilze France, Gunta Lāce, Ligita Pickaine, Anita Miķelsone. Sin 2X = Sin (x+x ) = Sin x Cos x + Cos x Sin x = 2 Sin x Cos x. Because whether you write sin x Cos x or Cos x Sin x it is the same thing. You can verify this by assigning x a value of any angle 30, 45, 60 degrees or pi/6, pi/4, pi/3 etc. Illustration of a unit circle (circle with a radius of 1) superimposed on the coordinate plane with the x- and y-axes indicated.

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
