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)= i.e, or SEC(iz). where 'i' is the imaginary unit and
• Also relation between Hyperbolic & Trignometric function is Sec(iz) = Sech(z) & Sec(iz) = Sec(z)

Examples

SECH(z)

• z is any real number.
