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.
All documents are also available to download in PostScript.

Does there exist a number that doubles in value when its digits are reversed?
Simple properties of real numbers aid in a rigorous proof of this unintuitive result.
A calculus proof of a frequently-cited pre-calculus concept.
A homemade compass-and-straightedge method that demonstrates the inefficiencies of certain forms of mathematics.
Finding the width of a hallway with two criss-crossing ladders is tricky, but finding integer-length ladders that yield an integer-width hallway might not be so hard.
In a reversal of the classic Greek problem, given a certain geometric construction, try to find the angle it trisects.
Where is the flaw in this analysis-based proof of a well-known facetious result?
Using explicit boundary conditions in searching for potential solutions rather than validating candidate solutions.
An elementary method of determining the area under the famous probability curve is unit.
A topological proof that there are infinitely many primes serves a surprisingly-elegant first step into the subject.
Recreating a little-known geometric argument that underpins the terms of the famous Maclaurin series for sine and cosine.
A straightforward problem with some definitions that lead to important constraints on its solutions.
A factorization method that hides it mathematically-correct processes behind some ugly and unjustifiable manipulations.
The machinery behind an elegant cosine-based method of finding roots of cubic equations.
My understanding of how each term in a quadratic equation affects its roots, and where the terms of the quadratic formula come from.
