The purpose of research is an effective usage of modern metod for study of extremal problem of analyses. The results of research: the best quadrature formulae for spacies of periodic function with continuous r th derivative are obtained, the asymptotically exact estimates of the pointwise approximation are established, the new exact inequalities of Kolmogorov type are obtained.
