How to determine the sum of interior angles for any polygon

👉 Learn about the interior and the exterior angles of a polygon. A polygon is a plane shape bounded by a finite chain of straight lines. The interior angle of a polygon is the angle between two sides of the polygon. The sum of the interior angles of a regular polygon is given by the formul

The Homework Problem That Started as a Phd Thesis: 14 set theorem

In a handful of introductory topology textbooks, Kuratowski's 14 set theorem is given as an exercise despite it being one of the results proven as a part of his phd thesis in 1922. This homework problem that started out as a phd thesis is not an easy exercise if you don't know how to think

Taste of topology: Open Sets

Here I give a taste of topology by defining the notion of an open set, give examples, and show its main properties. I further define the notion of an interior. Enjoy this little topology and analysis extravaganza. More videos can be found on my playlist below. Closed Sets: https://youtu.b
