The scale factors are only present in the determinant for the curl. This has to do with the definition of the curl and its use of length and area.

When I do the right hand side I get exactly the same thing above but doubled. So in affect I'm deriving 1 = 2. I'm sure there is an easy identity to manipulate the cross and dot products, but the ... WebFurthermore we have for. ∇. ( A × B) = ∂ ∂ x ( a y b z − a z b y) + ∂ ∂ y ( a z b x − a x b z) + ∂ ∂ z ( a x b y − a y b x) Now lets solve for the right hand side and see if we obtain e.g. the same argument for the partial derivative of ∂ ∂ x:
WebI am looking at the proof of the following identity: a x (b x c) = (a.c)b - (a.b)c.
