| Dec 27, 2017 at 21:04 | comment | added | Igor Rivin | @DimaPasechnik If you take a sine polynomial $p(x)$ and apply the operation I describe (take a polynomial with all degrees odd, and positive coefficients), you will get another sine polynomial of the desired type. I did an edit to clarify slightly. | |
