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 & y are the real number
  • 'i' is the imaginary unit
  • 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

IMCOS(iz)

  • iz is the complex number.
