Abstract
- The article presents a mathematical problem that uses Fourier sums to estimate simultaneous approximation of functions and their derivatives. It discusses the problem of simultaneous approximations in C of functions of class Wrr H[ω] and their derivatives by fourier sums. It adds that the numbers k1, k2.. km must be integers.
