Hyperbolic functions are functions similar to ordinary trigonometric functions, but based on the unit hyperbola () rather than the unit circle (). The most common are hyperbolic sine (sinh), hyperbolic cosine (cosh), and hyperbolic tangent (tanh), their reciprocals hyperbolic cosecant (csch), hyperbolic secant (sech), and hyperbolic cotangent (coth), and their inverses.
