### How to detect loops in a vector field?

Maybe you can transform this into an easier problem: If you were instead looking for lines that are at any point perpendicular to your vector field: (that's easy, it's just a coordinate ...

### Derivatives of vectors

Here's how you should probably do this: vec = Array[v, 3] D[vec.vec, vec.{0, 0, 1}] (* {v[1], v[2], v[3]} *) (* 2 v[3] *) I'll just make a couple of points about ...
