We study the periodic solutions of the second--order differential equations of the form x x^n = f(t), or x $^ n = f(t) are only continuous in t and locally--Lipschitz in x. ^ n = f(t), where n=4,5, f(t) is a continuous T--periodic function such that _0^T f(t)dt 0, and is a positive small parameter. Note that the differential equations x x^n = f(t) are only continuous in t and smooth in x, and that the differential equations
