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 & Trigonometric function is &
• SECH(-z) = SECH(z)

## Examples

SECH(z)

• z is any real number.
 SECH(z) Value SECH(0) 1 SECH(10) 0.00009079985933781728 SECH(7) 0.001823762414
