    Abstract: Recently, the monotone decreasing coefficients of sine series has been generalized by class
of p-supremum bounded variation sequences. Further, class of p-supremum bounded variation sequences can
be generalized by class of p-supremum bounded variation difference sequences. In this study we compute error
about approximation of sine series with coefficient from class p-supremum bounded variation difference
sequences.
