Title: Up and down and down and up

Abstract: We look at the number of ways of arranging 1, 2, 3, $\ldots$, $n$, so that the numbers go up, then down, then back up, and so on. While there isn’t a simple closed formula for this number as a function of $n$, there is a very simple way of analyzing the number and a simple connection to the Taylor series of some very familiar functions.
