It can be shown that for any real number x > 0, not only does n! eventually overtake xn , but the n ratio x ! → 0 as n → ∞.2 n Applications of factorials in the wild often involve counting arrangements. For example, if you have fifty songs on your mp3 player and wish arrange these songs in a playlist in which the order of the 2 This fact is far more important than you could ever possibly imagine. 9.4 The Binomial Theorem 583 songs matters, it turns out that there are 50! different possible playlists. If you wish to select only ten of the songs to create a playlist, then there are 50! such playlists. If, on the other hand, you just 40! want to select ten song files out of the fifty to put on a flash memory card so that now the order 50! no longer matters, there are 40!10! ways to achieve this.3 While some of these ideas are explored in the Exercises, the authors encourage you to take courses such as Finite Mathematics, Di...
