I have used the more universal i throughout. A complex number, z, is of the form: or, using polar coordinates: where x and y are real numbers and: The modulus of a complex number is: The argument of a complex number is: The conjugate of a complex number is: In the following lines: For : When  is measured in radians: The exponential form of a complex number:
