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.

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 ...

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.

Cosecant, Secant, and Cotangent - SparkNotes
In addition to sine, cosine, and tangent, there are three other trigonometric functions you need to know for the Math IIC: cosecant, secant, and cotangent.

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.
