Summary of Chapter 3 | Complex Number | Finding Reference Angle for Argument | June 2017

The idea of reference angle is being used both in chapter 2 and chapter 3. 

In Chapter 3, complex number, we will use the reference angle,α to find the argument,θ of a complex number by using
Engineering Mathematics 1 | DBM1013

Importantly, the characteristics of reference angle,α are as below
  1. It less than 90 degree
  2. It is always positive
  3. and Do Not bring negative sign of y and/or x during calculation to obtain reference angle.
