10 Complex Numbers and the Unit Circle

This video introduces the idea of the argument and the polar form for complex numbers that lie on the unit circle in the complex plane. Animations are given of both positive and negative rotations to determine arguments and hence the polar form for i, -1, and -i. The modulus and cartesian form of a complex number are also mentioned. Opportunities are given for the viewer to attempt questions during the video. This is No10 in my Complex Analysis video series
