- where z is any real number
- This function gives the hyperbolic Secant of 'z',
- It is also called as Circular function.
- SECH is the reciprocal of COSH function.
- SECH(z)= i.e, or SEC(iz). where 'i' is the imaginary unit and
- Also relation between Hyperbolic & Trigonometric function is &
- SECH(-z) = SECH(z)
- z is any real number.
