 +====== Inverse Hyperbolic Cosine (Expression Function) ======
  
 +===== Purpose =====
 +The **Inverse Hyperbolic Cosine** function (ACOSH) is used to calculate the inverse, arc, [[Expression Function - Hyperbolic Cosine|hyperbolic cosine]] of a value given in radians, degrees, or gradians. ​
 +
 +{{::​acosh_initial.png?​direct&​600|}}
 +
 +===== Parameters =====
 +The **Inverse Hyperbolic Cosine** function has two parameters, the first of which is required:
 +
 +==== Value ====
 +
 +Allowed Inputs: [[Field|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"​.
