Centralizer of a set in a group
A centralizer consider a subset of the set that constitutes a group and included all the elements in the group that commute with the elements in the subset. That's a mouthful, but in reality, it is actually an easy concept. In this video I also prove that the centralizer of a set in a gr

Centralizer of an element in the dihedral group of order 6
Before we go on to the stabilizer of a set in a group, I want to use the dihedral group of order 6, select one of its elements and then go through the whole group to show that there are element that commute with this chosen element. I will do this wil the help of Mathematica. A shoutout

From playlist Unit 1: Descriptive Statistics
The central limit theorem allows us to do statistical analysis through hypothesis testing. In short, is states that if we compile many, many means from sample taken from the same population, that the distribution of those means will be normally distributed.

Trigonometry X: the Law of Cotangents (and another lovely relation involving cotangents!)
Boy, oh boy this is a longish one. I prove the Law of Cotangents using the incenter of the triangle, after motivating the path with another way one might seek to prove the Law of Sines using the circumcenter of the triangle. After that, I demonstrate an equally lovely relationship betwee
