- where z is any real number
- 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 i=sqrt(-1).
- Also relation between hyperbolic &trignometric function is
- sec(iz)=sechz&sec(iz)=sec z
- z is any real number.
