The appoximation for continuous functions of monotonic type by the partial sums of Chebyshev-Fourier series has been investigated. An eromr estimate of the approximation is obtained. At the end three questions are raised, and it is the core of three quetihons that whether logn could be removed from some estimate expressions.
