I have a single nonlinear differential equation like(adsbygoogle = window.adsbygoogle || []).push({});

F(x2,dx1/dt,dx2/dt,d2x1/dt2,d2x2/dt2)=0

where x1=x1(t), x2=x2(t)

i.e. a second order non-linear DE with no implicit dependence on x1(t). I suppose solving it results (in general) that one of the variables would be dependent on the other.

How can I proceed with this?
