 # Inverse Hyperbolic Sine (Expression Function)

## Purpose

The Inverse Hyperbolic Sine function (ASINH) is used to calculate the inverse, arc, hyperbolic sine of a value given in radians, degrees, or gradians.

## Parameters

The Inverse Hyperbolic Sine function has two parameters, the first of which is required:

### Value

Allowed Inputs: field value or number

The first required parameter is the value that the inverse hyperbolic sine will be obtained from, either use the use the Query Builder to choose a field that contains the value or use type a value to enter a number.

### Angle Unit

Allowed Inputs: omitted, 'd', 'g'

The second parameter of the Inverse Hyperbolic Sine function is the output unit of the angle returned. If the angle unit is omitted or not recognized then radians will be be used. For an angle provided in degrees use 'd'. For an angle provided in gradians use 'g'. If the angle unit needs to be dynamically stored in a field then the advanced expression builder will need to be used.

## Output

The output of the Hyperbolic Sine function is an angle in radians, degrees, or gradians.

## Example

For example ASINH(0.547853473888) is “0.523598775598”, ASINH(0.547853473888,'d') is “30”, and ASINH(0.547853473888,'g') is “33.3333333333”.
