Complex numbers

About this unit

In this chapter we'll be extending the real number system to a larger system so as to solve equations which are not possible within the system of real numbers. We will finally get introduced to the infamous 'imaginary numbers' which you will soon realise are as 'real' as the real numbers that you are already quite familiar with. Equipped with this new weapon called complex numbers, we will revisit quadratic equations from a new point of view.
