Answer 2

The modulus can be found by using Pythagoras' Theorem where a complex number in the form z=a+bi has a modulus of sqrt(a^2+b^2). The argument of a complex number is the angle between the positive real axis and the line segment created by the complex number and the origin in the anticlockwise direction.
