Abstract:

In this paper we have defined the generalized Garrett-Stanojević cosine sums \[ {h_n}\left ( x \right ) = \sum \limits _{p = 0}^n {S_p^{r - 1}{\Delta ^r}{a_p}} \] and have proved that under suitable conditions ${h_n} \to h$ in the ${L^1}$-norm, where $h\left ( x \right ) = {a_0}/2 + \sum \nolimits _{n = 1}^\infty {{a_n}\cos nx}$. If $r = 1$, then ${h_n}\left ( x \right )$ reduces to the modified cosine sums introduced by Rees and Stanojević.
