Inverse Hyperbolic Cotangent -- from Wolfram MathWorld
The inverse hyperbolic cotangent coth^(-1)z (Beyer 1987, p. 181; Zwillinger 1995, p. 481), sometimes called the area hyperbolic cotangent (Harris and Stocker 1998, p. 267), is the multivalued function that is the inverse function of the hyperbolic cotangent.

Inverse hyperbolic functions - Wikipedia
In mathematics, the inverse hyperbolic functions are the inverse functions of the hyperbolic functions.. For a given value of a hyperbolic function, the corresponding inverse hyperbolic function provides the corresponding hyperbolic angle.

Express Sine in Terms of Cotangent - dummies
Even though each trigonometry function is perfectly wonderful, being able to express each trig function in terms of one of the other five trig functions is frequently to your advantage. For example, you may have some sine terms in an expression that you want to express in terms of cotangent, so that ...

Trigonometric Functions and Their Graphs: Co-functions
What about the co-functions, the secant, the cosecant, and the cotangent? The cosecant is the reciprocal of the sine. Wherever the sine is zero, the cosecant will be undefined, so there will be a vertical asymptote.
