Jan 2, 2026 · cotangent, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, is cot A = length of side adjacent to angle A/ length of side opposite angle A.

The trigonometric functions most widely used in modern mathematics are the sine, the cosine, and the tangent functions. Their reciprocals are respectively the cosecant, the secant, and the …

The cotangent of an angle in a right triangle is defined as the ratio of the adjacent side (the side adjacent to the angle) to the opposite side (the side opposite to the angle).

In a right triangle, the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side. In a formula, it is abbreviated to just 'cot'.

The cotangent of a sum can be represented by the rule: "the cotangent of a sum is equal to the product of the cotangents minus one divided by a sum of the cotangents."

Nov 26, 2025 · Discover everything you need to know about tangent and cotangent functions in this concise guide. Learn definitions and properties.

The cotangent function is defined and investigation of the graph of the general cotangent function and its properties such as range, period and asymptotes are also presented.

Cotangent (abbreviated cot or cot x) is one of the six core trigonometric functions, and it’s closely linked to tangent – making it a key concept for solving triangle problems, analyzing periodic …

Tangent is the ratio of sine and cosine. Thus, its reciprocal is the ratio of cosine to sine. It is called cotangent. (θ): all of the half- π π ’s. (θ): all of the whole- π π ’s. This means intercepts at the …
