ATANH(z)
- where z is any number between -1 and 1.
Description
- This function gives the Inverse Hyperbolic Tangent of a number.
- Here 'z' is any number between -1 and 1. ie
- Inverse Hyperbolic Tangent of a number is defined by
- TANH(-z)=-TANH(z). Also ATANH(TANH(z))=z
- ATANH(1)=Infinty
Examples
ATANH(z)
- z is any real number between -1 & 1.
| ATANH(z) | Value(Radian) |
| ATANH(0.1) | 0.100353477 |
| ATANH(0.75) | 0.97295507 |
| ATANH(-0.3) | 0.309519604 |
