Returns the inverse hyperbolic cosine of a number.
Deze functie werkt in Google Spreadsheets hetzelfde als in Excel — dezelfde syntaxis en argumenten.
ACOSH(number)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)Resultaat: 0
The inverse hyperbolic cosine of 1 is 0.
=ACOSH(10)Resultaat: 2.993222846
Calculates the inverse hyperbolic cosine of 10.
This error occurs if the input number is less than 1, as the inverse hyperbolic cosine is undefined for values smaller than 1.
