Wikipedia
cotangent
In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others. They are among the simplest periodic functions, and as such are also widely used for studying periodic phenomena through Fourier analysis. The trigonometric functions most widely used in modern mathematics are the sine, the cosine, and the tangent. Their reciprocals are respectively the cosecant, the secant, and the cotangent, which are less used. Each of these six trigonometric functions has a corresponding inverse function, and an analog among the hyperbolic functions. The oldest definitions of trigonometric functions, related to right-angle triangles, define them only for acute angles. To extend the sine and cosine functions to functions whose domain is the whole real line, geometrical definitions using the standard unit circle (i.e., a circle with radius 1 unit) are often used; then the domain of the other functions is the real line with some isolated points removed. Modern definitions express trigonometric functions as infinite series or as solutions of differential equations. This allows extending the domain of sine and cosine functions to the whole complex plane, and the domain of the other trigonometric functions to the complex plane with some isolated points removed.

cotangent
In mathematics, the cotangent of an angle in a right triangle is the ratio of the length of the adjacent side to the length of the opposite side. It is one of the basic functions in trigonometry, and is the reciprocal of the tangent function. It is usually abbreviated as "cot". In the unit circle, the cotangent of an angle is the x-coordinate divided by the y-coordinate.
Webster Dictionary
Cotangentnoun
the tangent of the complement of an arc or angle. See Illust. of Functions
Etymology: [For co. tangens, an abbrev. of L. complementi tangens. See Tangent.]
