A New Family of Nonnegative Sine Polynomials

Classical Analysis and ODEs 2017-08-04 v2

Abstract

We present a new family of sine polynomials that are nonnegative for all xx in [0,π][0,\pi]. We also characterize all nonnegative sine polynomials of degree 3 and all nonnegative cosine polynomials of degree 2. In the latest version, typos in (1.4) and (1.6) are corrected (with >= replaced by <=).
