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. 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
i.e. 2/e^z+e^-z or SEC iz.where 'I' is the imginary unit and i=sqrt(-1).Examples
SECH(z)
- z is any real number.
