Abstract
The rational fraction approximation is introduced by fraction series, and the existing principle of Pade approximation is given at the same time, and soleness principle, in combination with the knowledge of the linear algebra, the resolution of the linear system of equations, the features of determinate, and so on, this article gives the strict evidence. It is convenient to use rational fraction to approximate the fraction f(x) , and work out the approximate function value and it is accurate.
