Using the fact that we can write the vector cross-product in the form: (A× B)i =ε ijk Aj Bk ,
where εijk is the Levi-Civita tensor show that:
∇×( fA) = f ∇× A− A×∇f ,
where A is a vector function and f a scalar function.
Could you please be as descriptive as possible; as I'm not sure how to even start this problem.
