The prefix "co-" (in "cosine", "cotangent", "cosecant") is found in Edmund Gunter 's Canon triangulorum (1620), which defines the cosinus as an abbreviation of the sinus complementi (sine of the complementary angle) and proceeds to define the cotangens similarly. [51][52]

Mar 28, 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 other five trigonometric functions are sine (sin), cosine …

Die Bezeichnung „Kotangens“ entwickelte sich aus complementi tangens, also Tangens des Komplementärwinkels. [1] Die Wahl des Namens Tangens erklärt sich unmittelbar durch die Definition im Einheitskreis. Die Funktionswerte entsprechen der Länge eines Tangentenabschnitts:

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'. Of the six possible trigonometric functions, cotangent, secant, and cosecant, are rarely used.

Cotangent is one of the 6 trigonometric functions. It is usually referred to as "cot". Just like other trigonometric ratios, the cotangent formula is also defined as the ratio of the sides of a right-angled triangle. The cot x formula is equal to the ratio …

Cotangent calculator to easily calculate the cotan function of any angle given in degrees or radians. Calculate cot (x) with this trigonometry calculator.

The classical definition of the cotangent function for real arguments is: "the cotangent of an angle in a right‐angle triangle is the ratio of the length of the adjacent leg to the length to the opposite leg." This description of is valid for when the triangle is nondegenerate.

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]

Mit dem Cotangens (auch Kotangens, abgekürzt cot oder cotan) kannst du in einem rechtwinkligen Dreieck fehlende Seiten und Winkel bestimmen. Der Cotangens eines Winkels …
