Homework Statement


I need to write w^2 in suffix notation for a derivation I am doing, where w = del X u


Homework Equations



(del X u) = w

The Attempt at a Solution



I think it is Eijk(d^2uk/dxj)

where d is the partial derivative, E is the epsilon operator and ijk are suffix's, is this correct?

By w^2 do you mean [itex]w \cdot w[/itex]? What is [itex]\nabla \times u[/itex] in index notation? Then you need to write [itex](\nabla \times u) \cdot (\nabla \times u)[/itex] in index notation.
