Trigonometric functions - Wikipedia
The most familiar trigonometric functions are the sine, the cosine, and the tangent. Their reciprocals are respectively the cosecant, the secant, and the cotangent, which are less used in modern mathematics. The oldest definitions of trigonometric functions, related to right-angle triangles, define them only for acute angles.
Cotangent Definition (Illustrated Mathematics Dictionary)
Cotangent. more ... In a right angled triangle, the cotangent of an angle is: The length of the adjacent side divided by the length of the side opposite the angle. The abbreviation is cot cot(θ) = adjacent / opposite It is not commonly used, and is equal to 1/tangent. Sine, Cosine, Tangent.
Secant, Cosecant, Cotangent (solutions, examples, videos)
The cotangent function is the reciprocal of the tangent function. The abbreviation of cotangent is cot. The Reciprocal Trigonometric Functions are as follows: Example: Given that , and that θ is acute, find, without using a calculator, the value of a) sec θ. b) cot θ. Solution:

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. Note that the cotangent is not in as widespread use in Europe as are sinz, cosz, and...
Cotangent - math word definition - Math Open Reference
Cotangent can be derived in two ways: The inverse cotangent function - arccot. For every trigonometry function such as cot, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. So the inverse of cot is arccot etc.

Cotangent Calculator. The Cotangent is also called as the Inverse of tangent value. It is one of the basic trigonometric functions. It is just the inverse function of tan(x) or tangent. In other words, it could be referred to as the cos(x) divided by the sin(x). [Cosine/Sine].

cotangent cot ctg. The trig function cotangent, written cot θ. cot θ equals or .For acute angles, cot θ can be found by the SOHCAHTOA definition, shown below on the left. The circle definition, a generalization of SOHCAHTOA, is shown below on the right. f(x) = cot x is a periodic function with period π.
