| Abstract: | To popularize the polynomial interpolation,the polynomial interpolation and its error formula are derived by using elementary method with the base function of Lagrange interpolation in tridimensional space.In addition,the result is generalized to the n-dimensional space.At last,an example of numerical experiment was given. |
