WebIf curl of a vector field F is zero, then there exist some potential such that $$F = \nabla \phi.$$ I am not sure how to prove this result. I tried using Helmholtz decomposition: $$F = \nabla \phi + \nabla \times u,$$ so I need to show that $\nabla \times u=0$ somehow. multivariable-calculus Share Cite Follow edited Aug 4, 2016 at 16:14 Chill2Macht
