Hyperbolic Functions: The hyperbolic functions, such as sinh, cosh, tanh, and their inverses, are mathematical functions that are analogous to the trigonometric functions but are defined using the exponential function instead of the circular functions.
Inverse Hyperbolic Functions: The inverse hyperbolic functions, such as sinh⁻¹, cosh⁻¹, and tanh⁻¹, are the inverse functions of the hyperbolic functions, and they are used to find the angle whose hyperbolic function is a given value.
Hyperbolic Tangent: The hyperbolic tangent function, denoted as tanh, is a hyperbolic function that is the ratio of the hyperbolic sine function to the hyperbolic cosine function, and it is used to model various physical and biological phenomena.
