This function calculates the inverse hyperbolic cosine of the specified value.
ACOSH(value)
For the argument, you can specify any real number greater than or equal to 1.
This function is the inverse of the hyperbolic cosine, so ACOSH(COSH(n)) gives the result n.
Accepts numeric data. Returns numeric data.
ACOSH(B3)
ACOSH(R3C2)
ACOSH(1) gives the result 0
ACOSH(10) gives the result 2.9932228461
