SECH(z)

This function gives the hyperbolic Secant of 'z',
It is also called as Circular function.
SECH is the reciprocal of COSH function.
SECH(z)= $(cosh(z))^{-1}$ i.e, ${\frac {2}{e^{z}+e^{-z}}}$ or SEC(iz). where 'i' is the imaginary unit and $i={\sqrt {-1}}$
Also relation between Hyperbolic & Trigonometric function is $Sec(iz)=Sech(z)$ & $Sech(iz)=Sec(z)$
SECH(-z) = SECH(z)
