ACOSH(Number)
- is any real number.
- ACOSH() returns the inverse hyperbolic cosine of a number.
Description
- This function gives the Inverse Hyperbolic Cosine of a number.
- Consider '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
