Trigonometric functions - Wikipedia
The trigonometric functions most commonly used in modern mathematics are the sine, the cosine, and the tangent functions. Their reciprocals are respectively the cosecant, the secant, and the cotangent functions, which are less commonly used. Each of these six trigonometric functions has a corresponding inverse function and has an analog among the hyperbolic functions. The oldest definitions of ...
Cotangent | Definition, Formulas, & Facts | Britannica
Cotangent, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, iscot A = length of side adjacent to angle A length of side opposite angle A .The other five trigonometric functions are sine (sin), cosine (cos), secant (sec), cosecant (csc), and tangent (tan). From
Cotangent - Formula, Graph, Domain, Range | Cot x Formula
Let us learn more about cotangent by learning its definition, cot x formula, its domain, range, graph, derivative, and integral. Also, we will see what are the values of cotangent on a unit circle.
Tangent and Cotangent - Algebrica
Tangent and cotangent are trigonometric functions defined as the ratios of sine and cosine of an angle. They admit geometric interpretations on the unit circle, exhibit periodic behavior, and play a fundamental role in trigonometry, analytic geometry, and the study of complex numbers.
Law of cotangents - Wikipedia
In trigonometry, the law of cotangents is a relationship among the lengths of the sides of a triangle and the cotangents of the halves of the three angles. [1][2] Just as three quantities whose equality is expressed by the law of sines are equal to the diameter of the circumscribed circle of the triangle (or to its reciprocal, depending on how the law is expressed), so also the law of ...
Cotangent -- from Wolfram MathWorld
The cotangent function is the function defined by ... where is the tangent. The cotangent is implemented in the Wolfram Language as Cot [z]. The notations (Erdélyi et al. 1981, p. 7; Jeffrey 2000, p. 111) and (Gradshteyn and Ryzhik 2000, p. xxix) are sometimes used in place of .
