Using the definition of Levi-Civita and Kronecker delta symbols to prove the following identity \begin{eqnarray} \epsilon_{i\,j\,k}\,\epsilon_{l\,m\,n}\ &=&\ \begin{vmatrix} \delta_{il}&\delta_{im}&\delta_{in}\\ \delta_{jl}&\delta_{jm}&\delta_{jn}\\ \delta_{kl}&\delta_{km}&\delta_{kn} \end{vmatrix} \end{eqnarray}
