ACOSH(z)
- where z is any real number
Description
- This function gives the Inverse Hyperbolic Cosine of a number.
- Here 'z' is any positive real number i.e, .
- Inverse Hyperbolic sine of a number is defined by
- Also ACOSH(COSH(z))=z
- ACOSH(-2)=NAN , since z<1
.
Examples
ACOSH(z)
- z is any positive real number.
