What is cot degree?

A cotangent of an angle α is also equal to the ratio between its cosine and sine, so cotα = cosα / sinα. Following from the definition, the function results in an undefined value at certain angles, like 0°, 180°, 360°, and so on.

What is cot Theta?

Cot theta of a right-angled triangle is equal to the ratio of the length of the opposite side to the length of the adjacent side. It is also equal to the ratio of the cosine of the angle and the sine of the angle.

What is COS 30 in fraction?
