I'm in an intro course and my shaky ability to solve differential equations is apparent.(adsbygoogle = window.adsbygoogle || []).push({});

How would you go about solving

[itex]\ddot{r}[/itex]-r[itex]\ddot{\theta}[/itex]=0

[itex]\ddot{\theta}[/itex]+[itex]\frac{1}{r}[/itex][itex]\dot{r}[/itex][itex]\dot{\theta}[/itex]=0

It might be obvious. They're the geodesic equations for a 2d polar coordinate system (if i'm correct).
