Curl identity proofs

WebNB: Again, this isnota completely rigorous proof as we have shown that the result independent of the co-ordinate system used. 5.8 Some definitions involving div, curl and grad A vector field with zero divergence is said to be solenoidal. A vector field with zero curl is said to be irrotational. 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.
