TANH(z)
- where z is any real number
Description
- This function gives the hyperbolic Tan of 'z'.
- It is also called as Circular function.
- Here ie, or , where is the imginary unit and
- Also relation between Hyperbolic & Trigonometric function is &
- TANH(-z)=-TANH(z)
ie, 
or 
, where 
is the imginary unit and 
& 
Examples
TANH(z)
- z is any real number.
| TANH(z) | Value(Radian) |
| TANH(0) | 0 |
| TANH(1) | 1.5574077246549023 |
| TANH(10) | 1 |
