Their reciprocals are respectively the cosecant, the secant, and the cotangent functions, which are less used. Each of these six trigonometric functions has a corresponding inverse function …

Nov 14, 2025 · 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 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."

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'.

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 …

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.

Dec 4, 2025 · The cotangent function f (x) = cot (x) assigns to each angle x, expressed in radians, its corresponding cotangent value. Its graph is a periodic curve with a period of π and features …

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 …

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).

Dec 3, 2025 · The cotangent is implemented in the Wolfram Language as Cot [z]. The notations ctnz (Erdélyi et al. 1981, p. 7; Jeffrey 2000, p. 111) and ctgz (Gradshteyn and Ryzhik 2000, p. …
