Since many mathematical functions can not be directly applied in computer computation, they can be approximated by polynomial and piecewise polynomial. The general theory of this subject and its application in polynomial approximation have been very classical, but piecewise polynomial in the last twenty years has been greatly applied, and found a number of important theoretical properties, as well as many of the techniques to describe the accuracy of the book, the book is a thorough and systematic way of the current approximation method. Contents: Approximation Problems and existence of optimal approximation; uniqueness of best approximation; approximation operator and some function approximation; interpolation polynomial; difference quotient; polynomial approximation of.
