Calculates the hyperbolic arctangent of a value. Hyperbolic trigonometric functions are based on the hyperbola with the equation x2 – y2 = 1. These functions differ from those in standard trigonometry (also called circular trigonometry), whose functions are based on the unit circle with the equation x2 + y2 = 1. However, they share many similar identities, such as sinh2 x + cosh2 x = 1, where h represents hyperbolic.

Hyperbolic functions have many useful applications in engineering, such as electrical transportation (to calculate length, weight, and stress of cables and conducting wires), superstructure (to compute elastic curves and deflection of suspension bridges), and aerospace (to determine ideal surface coatings for aircraft). In statistics, the inverse hyperbolic sine is used in the Johnson transformation to transform the data so it follows a normal distribution. Normality is a necessary assumption for some capability analyses.


For a specified value of x, tanh x = sinh x / cosh x, where h represents hyperbolic.

The inverse of the function is atnh x (tanh−1 x).
