摘要
本文借助于有限区间上的台劳定理,对于具有偶数阶光滑的周期函数类,构造出了单边逼近算子,同时得到了逼近函数和原函数之间的逐点误差估计。
By means of the Taylor theorem on a finite interval,this paper generates a system of one-sided approximation operatiors fora periodic functional class which is even degrees smooth,And the point-wise convergence to the approximation function is obtained.
