All circles are the unit circle, scaled up. All continuously growing systems are e^ {rt}, scaled to some rate and time. When should I use e? Use e^ {rt} for things that change constantly (radioactive decay, populations). For growth based on discrete intervals (interest payments, combinatorics), (1 + rate)^ {time} is a better model.

Euler's number has several interesting properties that crosses the spectrum of mathematical topics. The differential of e x is e x. Its integral is simply e x + C (constant). If you took a differential of the natural logarithm of e x (ln e x) you would arrive at 1/x. In trigonometry, 'e' also helps to derive an interesting result: e ix ...
