The acosh function returns the inverse hyperbolic cosine. Therefore,Further information on the inverse hyperbolic functions can be found on Wikipedia
The Excel ACOSH function calculates the inverse hyperbolic cosine of a supplied number.
The format of the function is :
Where the number argument is a positive real number, which must be greater than or equal to 1, and which you want to calculate the inverse hyperbolic cosine of.
In the spreadsheet below, the Excel Acosh Function is used to calculate the inverse hyperbolic cosine of three different values.
Further information and examples of the Excel Acosh function can be found on the Microsoft Office website.
If you get an error from the Excel Acosh Function, this is likely to be one of the following:
|#NUM!||-||Occurs if the supplied number argument is less than 1.|
|#VALUE!||-||Occurs if the supplied number argument is not a numeric value.|
