More Combinatorial Proofs via Flagpole Arrangements
DeTemple, Duane; Reynolds, H. David, II
College Mathematics Journal, v37 n4 p279-285 Sep 2006
Combinatorial identities are proved by counting the number of arrangements of a flagpole and guy wires on a row of blocks that satisfy a set of conditions. An identity is proved by first deriving and then equating two expressions that each count the number of permissible arrangements. Identities for binomial coefficients and recursion relations are obtained.
