Web1These vectors are also denoted ^{ ,^ , and k^, or ^x y ^and z. We will use all three notations interchangeably. 1 valid for all possible choices of values for the indices. So, if we pick, say, i= 1 and j= 2, (1.3) would read e^ 1e^ 2= 12: (1.4) Or, if … WebThe proof of this identity is as follows: • If any two of the indices i,j,k or l,m,n are the same, then clearly the left-hand side of Eqn 18 must be zero. This condition would also result in two of the rows or two of the columns in the determinant being the same, so therefore the right-hand side must also equal zero.
