Curl index notation
WebI'm having trouble with some concepts of Index Notation. (Einstein notation) If I take the divergence of curl of a vector, ∇ ⋅ ( ∇ × V →) first I do the parenthesis: ∇ i V j ϵ i j k e ^ k … WebNov 6, 2024 · Closed 5 years ago. ∇ ⋅ ( u × v) = ( ∇ × u) ⋅ v − ( ∇ × v) ⋅ u. Hi, the above is a vector equation, where u and v are vectors. I am trying to prove this identity using index notation. I am able to get the first term of the right-hand side, but I don't see where the second term with the minus in front comes from.
