We consider the problem of the approximation of functions, continuous on the semiaxis $[0,\infty)$ and for which the derivatives $f^{(\nu)}(0)$, $\nu=0,\dots,r-1$ exist at the point $x=0$, by the Vallée-Poussin means of partial sums of a special series in Laguerre polynomials.
Mots-clés : Laguerre polynomials, Vallée-Poussin means.
Keywords: special series, approximation properties
