چکیده
In the present article, approximation of function |sin x| s by partial sums rational trigonometric Fourier series is considered. An integral representation, uniform and point estimates for above-mentioned were obtained. Based on them, several special cases selection poles studied. case polynomial series, an asymptotic equality was found. A detailed study made a fixed number geometrically different poles.
