The Attempt at a Solution



I don't know how to choose u. I presume we look in 2D; I thought u should look something like:

[tex]u = \left[ \begin{array}{c} \psi \\ \psi \end{array} \right] [/tex]

and [tex] c= \phi [/tex] but that isn't correct.

How about picking two vector fields? Pick u=(psi,0) for the first part and u=(0,psi) for the second part.
