Trigonometric functions - Wikipedia
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 cotangent functions, which are less used. Each of these six trigonometric functions has a corresponding inverse function, and an analog among the hyperbolic functions.
Cotangent - Math Open Reference
Definition and meaning of the math word cotangent. Large and negative angles. In a right triangle, the two variable angles are always less than 90° (See Interior angles of a triangle).But we can in fact find the cotangent of any angle, no matter how large, and also the cotangent of …

Feb 14, 2025 · 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 …
Cotangent - Formula, Graph, Domain, Range | Cot x Formula
It is usually denoted as "cot x", where x is the angle between the base and hypotenuse of a right-angled triangle. Alternative names of cotangent are cotan and cotangent x. 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 ...

Juan Sánchez Cotán - Wikipedia
Brígida del Río, the Bearded Lady of Peñaranda; 1590, 102 × 61 cm, Prado Museum.. Sánchez Cotán was born in the town of Orgaz, near Toledo, Spain.He was a friend and perhaps pupil of Blas de Prado, an artist famous for his still lifes whose mannerist style with touches of realism the disciple developed further. Cotán began by painting altarpieces and religious works.
Cotangent Calculator - Calculate cot (x) - Inch Calculator
If your calculator doesn’t have a cot or cotan button, you can enter the tangent of the angle and then press 1/x or the reciproc button to find cotangent.
Cotangent -- from Wolfram MathWorld
Mar 5, 2025 · 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 .Note that the cotangent is not in as widespread use in Europe as are , , and , although it does appear explicitly in various German and Russian handbooks (e.g., Gradshteyn ...
