SECH(z)


  • where z is any real number

Description

This function gives the hyperbolic secant of 'z',also it is called as circular function.
SECH is the reciprocal of COSH function.SECH
z=(cosh z)^-1.i.e. 2/e^z+e^-z or SEC iz.where 'I' is the imginary unit and i=sqrt(-1).
Also relation between hyperbolic &trignometric function is sec(iz)=sechz&sec(iz)=sec z

Examples

SECH(z)

  • z is any real number.
