IMCOSH(ComplexNumber)

This function gives the hyperbolic cosine (cosh) value of a complex number.
Consider 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.
$Cosh(ix)={\frac {e^{ix}+e^{-ix}}{2}}=Cos(x)$
$cosh(x+iy)$ is defined by $cosh(x+iy)=(cosh(x).cos(y))+i.(sinh(x).sin(y))$
