## 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?
