Excel ACOSH Function
The ACOSH function returns the inverse hyperbolic cosine of a number.
Syntax
=ACOSH(number)
Arguments
- number (required): The value for which you want to calculate the inverse hyperbolic cosine. Note: The number must be greater than or equal to 1.
Return Value
The ACOSH function returns a numeric value.
Function Notes
- The inverse hyperbolic cosine is the value whose hyperbolic cosine is number, so the result of =ACOSH(COSH(number)) is number itself.
- ACOSH returns the #NUM! error if number < 1.
- ACOSH returns the #VALUE! error if number is not numeric.
Example
To calculate the inverse hyperbolic cosine of the numbers listed in the table as shown below, please copy or enter the below formula in the top cell (D6) of the result list, and press Enter to get the result. Then select the result cell, and drag the fill handle (the small square in the lower-right corner of the selected cell) down to apply the formula to the below cells.
=ACOSH(B6)
Instead of a cell reference, you can type the actual number value in the formula as shown below.
=ACOSH(1)
