Dec 26, 2010 at 2:04 | comment | added | fedja | Now, why do you want to bound it by a "simpler" function (clearly, it is assumed to be "simpler" for some particular purpose but until we know what that purpose is, it is hard to tell what is helpful and what isn't.) | |
Dec 26, 2010 at 0:39 | comment | added | J. M. isn't a mathematician | Your function can be expressed in terms of the Chebyshev polynomial of the second kind: $$\frac1{n}U_{n-1}(\cos\omega)$$ | |

removed the tag "triangulated categories" (which is clearly irrelevant)
