ACOSH
This function calculates the inverse hyperbolic cosine of the specified value.
Syntax
ACOSH(value)
Arguments
[Required] For the argument, you can specify any real number greater than or equal to 1.
Remarks
This function is the inverse of the hyperbolic cosine, so ACOSH(COSH(n)) gives the result n .
Examples
ACOSH(B3)
ACOSH(R3C2)
ACOSH(1) gives the result 0
ACOSH(10) gives the result 2.9932228461
ACOS(R3C2)
