Lattice paths and positive trigonometric sums
A trigonometric polynomial generalization to the positivity of an alternating sum of binomial coefficients is given. The proof uses lattice paths, and identifies the trigonometric sum as a polynomial with positive integer coefficients. Some special cases of the q-analogue conjectured by Bressoud are established, and new conjectures are given.
