IMCOS(iz)

• where 'iz' is the complex number

Description

• This function gives the cos value of 'iz'.
• Where iz is 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 $cos(x+iy)=cos(x)cosh(y)-isin(x)sinh(y)$

Examples
