IMCOS (ComplexNumber)

where 'ComplexNumber' is any complex number of the form x+iy.
- IMCOS(), returns the cosine of a complex number.

This function gives the cos value of any complex Number.
Consider the complex number in the form of $x+iy$
x & y are the real number
'i' is the imaginary unit $i={\sqrt {-1}}$
Also x is called the real part & y is the imaginary patr of a complex number.
COMPLEX is the function used to convert Real & Imaginary numbers in to a complex number.
$cos(x+iy)$ is defined by $cos(x+iy)=cos(x)cosh(y)-isin(x)sinh(y)$
