100/9899, what an amusing (gentle ab)use of generating functions. It probably says something that we just finished those in my combinatorics class, yet we never got to see this wonderful trick =)
In the same vein, 99...9/99...8 has a fun pattern as well. I'm feeling totally cheated here. I suppose i should try to read Knuth's treatment of GFs and see if they make sense at this point. |
