IMCOTH(iz)

Description

This function gives the hyperbolic cotangent (coth) 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.
$coth(x+iy)$ is defined by $coth(x+iy)=cosh(x+iy)/sinh(x+iy)$
