Best universal approximations of continuous functions by generalized multiplications.

  • L. Grinchenko Lutsk National Technical University
Keywords: polynomials of best approximation, generalized polynomials, Chebyshev polynomials.


Two methods of approximate construction of polynomials of best approximation are proposed. An approach is presented which, using a finite number of steps, allows us to construct a polynomial of best approximation to a function  on a set that consists of a finite number of points.
