Abstract: | In this article,a new numerical solution of ordinary differential equations,which was different from the traditional numerical solutions,was presented.We would solve the problems such as first-order ordinary differential equations,explicit second-order differential equation and Vander Pol equation by this new method.And the relative errors were less than 0.5% |
