I need to calculate Ax(BxC) -A, B, C are vectors, apart from bac-cab rule, I need to get it by epsilon ijk -Following I will note it by e(ijk).
I expect answerer to know kronecker delta equation and vector multiplications.
The Attempt at a Solution
(BxC)(j) = e(mjn)B(n)C(m)
After that part I'm stuck. As you can see below, I rotate the ijk's and mjn's to match j's at the end, but I fail.
Can you help me after that?
Lettters in parantheses (i, j, k, m, n) are supposed to indicate the indices.
