Normal subgroups are a powerful tool for creating factor groups (also called quotient groups). In this video we introduce the concept of a coset, talk about which subgroups are “normal” subgroups, and show when the collection of cosets can be treated as a group of their own. As a motivation, we will begin by discussing…

This video introduces the units modulo n and gives a sketch of a proof showing that they form a group under multiplication modulo n.

When learning about groups, it’s helpful to look at group multiplication tables. Sometimes called Cayley Tables, these tell you everything you need to know to analyze and work with small groups. It’s even possible to use these tables to systematically find all groups of small order! If you’d like to help us make videos more…

A simple proof of the very important and useful trigonometry Identity sin^2(x) + cos^2(x) = 1 is shown. Also the notation for squaring trigonometric functions is shown. Since the proof requires the use of the Pythagorean theorem, this identity is called the Pythagorean trigonometric identity.
