Mathematics has always been of great interest to me. I received an BS in mathematics in 2015, and I worked for several years as a specialized instructor for a private tutoring company. While I'm nowhere near an expert, I still find many topics in math to be fascinating.
Here I write documents about various facets of math that catch my attention. Not only do I hope to share some of my passions, but I also want to get practice and experience in using digital tools to study and present mathematical topics. Updates will be irregular and perhaps infrequent, as learning these tools can take quite some time.
All documents are also available to download in PostScript.
