Abstract: Continuing the work of [1], this paper considers mainly the approximation to the n-th derivatives of functions, and develops an effective algorithm with its convergance and error astimate by the method of numerical integration. As an application, the algorithm is used to evaluate the integration of highly oscillatory functions and proves efficient.

Key words: numerical approximation, algorithm, error estimation
