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)

## Examples

SECH(x)

• x is any real number.
