Cotangent | Definition, Formulas, & Facts | Britannica
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.
Trigonometric functions - Wikipedia
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 and has an analog among the hyperbolic functions.
Cotangent: Introduction to the Cotangent Function - Wolfram
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."
Cotangent - Math Open Reference
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'.
What is cotangent - Trigonometry
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 functions, and working in fields like engineering and navigation.

Cotangent in Trigonometry Explained Simply - Andrea Minini
Since the cotangent is a periodic function with a period of π, it can be studied within the interval (0, π). In this interval, the cotangent is a continuous, monotonic, and decreasing function.
Cotangent - Formula, Graph, Domain, Range | Cot x Formula
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).
Cotangent - from Wolfram MathWorld
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. xxix) are sometimes used in place of cotz.
