I have ##\frac{d^2x(t)}{dt^2} + B(x(t))^3 = 0## for a system where I know the initial conditions and where B is a constant that's constructed from the properties of the system. I would like to find ##x(t)##.(adsbygoogle = window.adsbygoogle || []).push({});

I've modelled the system in Python and produced some graphs. I know that ##x(t)## is some periodic function.

Could somebody name the method that I should study so that I can get a solution?
