Videos: Graph theory

Some videos on graphs and graph theory:


A short video about the historical origins of graph theory, with the “Seven Bridges of Königsberg” problem that the famous mathematician Leonhard Euler investigated in the 1730s:

Another couple of videos (from a YouTube channel that has a Discrete Math course playlist!) that introduce graph theory and does more of the math involved with the Bridges of Königsberg, introducing the idea of Euler paths and Euler circuits:

Here is a video introducing “the traveling salesmen problem”–a famous and important “optimization” problem in graph theory that has led to a lot of work in computer science (there are entire books about it–a good introductory one that is available online via the CityTech Library is In Pursuit of the Traveling Salesman: Mathematics at the Limits of Computation) by William Cook:

That YouTuber (MinuteMath) has multiple videos about graph theory–here is an introductory one:

A video on how map apps (e.g. GoogleMaps) find the shortest route (through a graph!):

About the MAT 1275 Course Hub

The Course Hub is a central resource created by the Mathematics Department for information and resources related to MAT 1275 Precalculus. Whether you are a student in the course or a faculty member teaching it, we hope you will find useful material there. Some of the resources you will find include:

  • Online Lessons. Here you will find (optional) online lessons for each day of class. If you missed a day of class, or you have questions, this is a great place to go!
  • WeBWorK Resources for Students and Faculty. Need help with WeBWorK? Whether you are a student stuck on a problem in the homework, or a faculty member trying to create a quiz, there are resources to help.
  • Video Resources. Stuck on a topic? Already looked at the online lesson? You can find additional videos for most topics here, including many examples worked out in full, created or selected by City Tech faculty.
  • Faculty Training and Support. Includes more general (non-WeBWorK) topics like: How do I create a discussion board in my course? How do I collect student work using DropBox? Etc.
