(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A vector field V is not irrotational.Show that it is always possible to find f such that fV is irrotational.

2. Relevant equations

3. The attempt at a solution

\nablax[fV]=f\nablaxV-Vx\nablaf

I have to equate the LHS to zero.But then,how can I extract f out of the resulting equation?

Please help
