The cosine of the angle 30° is a value representing the ratio of the length of the adjacent side (the angle under consideration) to the length of the hypotenuse. In trigonometry we mathematically write cos 30°, and its exact value in fractional form is **√3/2**.

It follows that **sin 30° = cos 60° = 1/2** and sin 60° = cos 30° = √3 / 2.

The value of cos 30 degrees is 0.8660254. . .. Cos 30 degrees in radians is written as **cos (30° × π/180°)**, i.e. H. cos(π/6) or cos(0.523598…).

Cot 30 degrees is the value of the trigonometric cotangent function for an angle of 30 degrees. The value of Cot 30° is **√3 or 1.7321 (approximately)**.

The exact value of sin 30 degrees is **0.5**.

The exact value of cos(30) is **√32** .

In trigonometry, the tangent of an angle in a right triangle is equal to the ratio of the opposite side and the adjacent side of the angle. Tan 30 degrees is also represented by **tan π/6** radians. The exact value of tan 30° is 0.57735.

The value of cos 60 is **1/2**.

Sin 30 formula: Sin 30 degrees is equal to cos 60 degrees. The value of sin 30 degrees is **1/2**.

The value of cos 1 degree is 0.9998476. . .. Cos 1 radian degree is written as **cos (1° × π/180°)**, i.e. H. cos(0.017453…). In this article, we will discuss the methods of finding the value of cos 1 using examples. Cos 1°: 0.9998476. . .

Cos theta or cos θ is **the ratio of the adjacent side to the hypotenuse, where θ is one of the acute angles**.
