## Definitions

### General

The inverse hyperbolic sine function, in modern notation written as arsinh(t) or arcsinh(t) or sinh^{-1}t, gives the value x (hyperbolic angle), so that:

The inverse hyperbolic sine function accepts arguments from the whole real space. Since the hyperbolic sine is defined through the natural exponential function , its inverse can be defined through the natural logarithm function, using the following formula, for any real x:

### Properties

The derivative of the inverse hyperbolic sine function is:

The integral of the inverse hyperbolic sine function is given by:
