Abstract:
Using the improved L_P method, the authors seek to solve a class of problems of square strongly nonlinear free oscillations and of strongly nonlinear nonoscillations. Their first_order approximate solutions which has high accuracy are obtained. The method of this paper is different from the known L_P methods.
