| Abstract: | In this paper, using the improved L-P method, the author seeks to solve the initial value problems of the strongly nonlinear Duffing equation and a class of nonoscillation type differential equation. Its calcultation process is quite simple and the accuracy of the results of this paper is better than that of the improved L-P method proposed by ZHANG Y. Q2]. |
| Keywords: | singular perturbation improved L-Pmethod strongly nonlinear duffing equation |
