These are the EOMs for a 4D space-time that has a plane singularity at x=0. They are simpler than most, but as I've confessed before, I need help with even the simplest DE's. This is not a home-work question.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]x\frac{d^2\tau}{dt^2} - \frac{d\tau}{dt}\frac{dx}{dt} = 0[/tex]

[tex]x^3\frac{d^2x}{dt^2} + \frac{m^2}{2}(\frac{d\tau}{dt})^2 - \frac{x^2}{2}(\frac{dx}{dt})^2 = 0[/tex]

Any solutions gratefully received and will be acknowledged.
