Adding basic fractions by finding a common denominator.

Simple example of how to add basic fractions by finding a common denominator. Real life example: the number of quarters played over the course of 4 games by Lebron James (Basketball).

Introduction - motivation to finding the roots of acomplex number. Also explains how to plot complex numbers known modulus and angle and covers when two complex numbers are equal.

Example of getting the Cartesian form of a complex number if the polar form is known.

This screencast gives an example of a projectile in 2D space where gravity is the only force acting. Vector methods are hence used to find the velocity and position vector of the projectile, given that its initial velocity and position are known.

An example is given of solving an equation of the form det(A-lambda*I)=0, where in this case A is a 2x2 matrix, I is the unit matrix and lambda is the scalar that we solve for

Covers the grahical representation of a complex number in the Argand diagram including a couple of examples.

General explanation is given of how a complex number in Cartesian form can be converted to polar form z=rcis(@) and then 3 examples are given to illustrate this

Three examples are given to demonstrate how to convert complex numbers written in exponential polar form into Cartesian form.
