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 Failed to parse (Conversion error. Server ("https://wikimedia.org/api/rest_") reported: "Cannot get mml. Server problem."): {\displaystyle Acosh(z)=loge(z+{\sqrt {z^{2}-1}})}
- Also ACOSH(COSH(z))=z
- ACOSH(-2)=NAN , since z<1
