Beta算子的导数对一类函数的逼近速度
On the Rate of Convergence of Functions and Their Derivatives by Beta Operators
【摘要】 利用渐近分析的方法讨论了Beta算子的导数对一类函数的逼近速度 ,获得了类似孙燮华的结果
【Abstract】 The author uses Laplace and Bojanic method to study the rate of convergence of functions and their derivatives by Beta operator and obtain degree of approximation.
