Homework Statement
evaluate [tex]\epsilon_{ijk}\epsilon_{ijk}[/tex] where \epsilon is is the antisymetric levi-civita symbol in 3D
Homework Equations
determinant of deltas = product of levi-civita -> would take ages to write out.
The Attempt at a Solution
[tex]\epsilon_{ijk}\epsilon_{ijk}=\delta_{kk}\delta_{ll}-\delta_{lk}\delta_{kl}=1-2\delta_{lk}[/tex]
But i have a feeling the answer is 3? (because of this)
