On the Middle Coefficient of a Cyclotomic Polynomial

Gregory Dresden

In this article, we provide a short and elementary proof of the following result: For $n \geq 3$ the middle coefficient of $Φ_{n} (x)$ is either zero (when $n$ is a power of $2$ ) or a…

Two Irrational Numbers That Give the Last Non-Zero Digits of $n!$ and $n^{n}$

Gregory Dresden

If we form a decimal where the nth digit is the last non-zero digit of $n!$ (likewise, the last non-zero digit of $n^{n}$ ), we obtain an irrational number
