Trigonometric functions - Wikipedia
The most familiar trigonometric functions are the sine, the cosine, and the tangent. Their reciprocal 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.

Mathwords: Cotangent
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.

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.

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.
