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)
