IMSECH(iz)

• where iz is the complex number

Description

• This function gives the hyperbolic SECANT value of a complex number.
• Where 'iz' is the complex number in the form of $x+iy$
• x & y are the real numbers.
• 'i' is the imaginary unit $i={\sqrt {-1}}$
• Also x is called the real part & y is the imaginary part of a complex number.
• COMPLEX is the function used to convert Real & Imaginary numbers in to a complex number.
• $sech(x+iy)$ is defined by $sech(x+iy)=1/cosh(x+iy)$

Examples
