Abstract
Let $f(x)$ be a function of bounded variation on $[-1,1]$ and $S_n (f; x)$ the $n$th partial sum of the expansion of $f(x)$ in a Chebyshev series of the second kind. In this note we give the estimate for the rate of convergence of the sequence $S_n (f; x)$ to $f(x)$ in terms of the modulus of continuity of the total variation of $f(x)$.
