A complex number has the form a+bi. We call a the 'real' bit (ie. the bit on a regular number line) and b is the 'imaginary bit. Multiplying complex numbers is done in a very similar way to multiplying out b...

First, we need to rearrange the equation into a quadratic. A quadratic equation will always have a squared element. To this, we move everything over to the left hand side of the equation and set it equal to ...

A complex number is a number made up of a real and imaginary part.

Proof by Induction: The method of Proof by Induction is a simple but very powerful technique. It involves 3 steps: 1) Showing a claim is true for a basic integer value of n (e.g. 0 or 1) 2) Assuming the clai...

A complex number has the form a+bi. We call a the 'real' bit (ie. the bit on a regular number line) and b is the 'imaginary' bit. To add or subtract complex numbers you just add the real bits of both togethe...
