A colleague of mine scrawled out some equations on a whiteboard a few days ago. As far as I can tell, they are a set of cross-coupled, vector-valued, two-dimensional, first-order nonlinear differential-algebraic equations.

I don't know what context exactly they are from, but IIRC they have something to do with the intercept of ballistic trajectories.

I've tried pretty much every trick in the book to sort this out. They're not seperable, they don't match any well-studied nonlinear ODE, and none of the integral transforms are of any help.

Let's see if anyone has any ideas. Equations are spread across three pictures.
