SECH(z)

• where z is any real number

Description

• 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 &trignometric function is
• sec(iz)=sechz&sec(iz)=sec z

Examples
