Any real number greater than or equal to 1.
The ACOSH function calculates the inverse hyperbolic cosine of a given number. The number must be greater than or equal to 1, otherwise the function returns a #NUM! error.
=ACOSH(1)→0The inverse hyperbolic cosine of 1 is 0.
=ACOSH(10)→2.993222846Calculates the inverse hyperbolic cosine of 10.

Click on the cell where you want to display the result.
Enter the formula
Type =ACOSH(number) and replace 'number' with the value or cell reference you wish to calculate.
Press Enter
Press the Enter key to calculate the inverse hyperbolic cosine.
This error occurs if the input number is less than 1, as the inverse hyperbolic cosine is undefined for values smaller than 1.
