Abstract: We gave a new method to find the periodic solution of differential equation. By the idea of Poincaré mapping, the problem of finding the periodic solution of differential equation can be converted into an optimization problem, then adopting the quasiNewton method to solve the corresponding optimization problem, we can find the periodic solution of the differential equation.
Key words: differential equations, periodic solutions, quasiNewton method
