ACOSH(Number)

is any real number.
- ACOSH() returns the inverse hyperbolic cosine of a number.

This function gives the Inverse Hyperbolic Cosine of a number.
Consider 'z' is any positive real number i.e, $z\geq 1$ .
Inverse Hyperbolic sine of a number is defined by $Acosh(z)=\log _{e}(z+{\sqrt {z^{2}-1}})$
Also ACOSH(COSH(z))=z
ACOSH(-2)=NAN , since z<1
