Abstract: The spatial approximation was studied and obtained by using the the B-spline interpolation operator based on the deduced combination of the and Jackon type theorem and then the higher approximation order is obtained in classical space.

Key words: B-Splinepolynomial reproducing, classical space, approximation order
