ACOSH

Definition: ACOSH is a function that returns the inverse hyperbolic cosine of a number. The inverse hyperbolic cosine of a number is the value whose hyperbolic cosine is a given number.

Syntax: =ACOSH(number)

Situation: This formula is suitable when you need to find the value whose hyperbolic cosine is a given number.

Example: If the hyperbolic cosine of a number is 2.5, the value can be found using the formula =ACOSH(2.5), which returns a value of 1.5668.
