Trigonometric functions - Wikipedia
In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are functions of an angle.They relate the angles of a triangle to the lengths of its sides. Trigonometric functions are important in the study of triangles and modeling periodic phenomena, among many other applications.

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.

Hyperbolic Cotangent -- from Wolfram MathWorld
The notation is sometimes also used (Gradshteyn and Ryzhik 2000, p. xxix). It is implemented in the Wolfram Language as Coth[z].. The hyperbolic cotangent satisfies the identity

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 all the functions […]

How to Graph a Cotangent Function - dummies
The parent graphs of tangent and cotangent are comparable because they both have asymptotes and x-intercepts. The only differences you can see are the values of theta where the asymptotes and x-intercepts occur. You can find the parent graph of the cotangent function f(x) = cot x, by using the same techniques you use to […]

SECANT,COSECANT,COTANGENT,trigonometry from A-level Maths ...
The secant,cosecant and cotangent are respectively the inverse of cosine, sine, and tangent. It is important to know what these functions look like graphically and how they compare.These ratios are common in a number of important 'Pythagorean identities'.

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.The size of the hyperbolic angle is equal to the area of the corresponding hyperbolic sector of the hyperbola xy = 1, or twice the area of the corresponding ...
