SECH(x)
- where x is any real number.
- SECH(), returns the inverse hyperbolic secant of a number.
Description
- This function gives the hyperbolic Secant of 'x',
- It is also called as Circular function.
- SECH is the reciprocal of COSH function.
- SECH(x)= i.e, or SEC(iz). where 'i' is the imaginary unit and
- Also relation between Hyperbolic & Trigonometric function is &
- SECH(-x) = SECH(x)
i.e, 
or SEC(iz). where 'i' is the imaginary unit and 
& 
Examples
SECH(x)
- x is any real number.
| SECH(x) | Value |
| SECH(0) | 1 |
| SECH(10) | 0.00009079985933781728 |
