Summary

This function calculates the inverse hyperbolic cosine of the specified value.

Syntax

ACOSH(value)

Arguments

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.

Data Types

Accepts numeric data. Returns numeric data.

Examples

ACOSH(B3)

ACOSH(R3C2)

ACOSH(1) gives the result 0

ACOSH(10) gives the result 2.9932228461

ACOS(R3C2)
