Description

This function gives the 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.
$sec(x+iy)$ is defined by $sec(x+iy)=[2(cosx.coshy+isinx.sinhy)]/(cos2x+cosh2y)$
