# Inverse Hyperbolic Cosine (Expression Function)

## Purpose

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

## Parameters

The Inverse Hyperbolic Cosine 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 cosine 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 Cosine 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 Cosine function is a number representing an angle in radians, degrees, or gradians.

## Example

For example ACOSH(1.14023832108) is “0.523598775605”, ACOSH(1.14023832108,'d') is “30”, and ACOSH(1.14023832108,\'g\') is “33.3333333333”.
