Thought I'd ask here as I can't seem to find much in the way of online resources.

Suppose I'm given some arbitrary vector field or . How would one go about (analytically) finding the family of flow lines for such a field? I know that a path is a flowline of some field if

So I'm assuming the problem reduces to solving a separable ODE, but I can't say I'm terribly familiar with solving such DE's with vector functions.

Any suggestions?
