| Abstract: | The Romberg formula is a successful example of peecise solution,wish is worked out from linear combination few approximate solutins. There are no conductions about the obvious form and the error equation of Romberg's quadrature formula in present literatures. In this paper, the obvious form of Romberg's quadrature formula and the error equation is presented. |
