Curl of a cross product index notation
WebJul 2, 2013 · However, for permutations without a sign change (ie even ones), this order of the indices can change without affecting the final answer. Moreover, since the cross product is NOT commutative but the dot product is, thus in the vector expression, only the order of the vectors in the cross product matters, not the order in the dot product.

These vectors have a scalar product given by and an outer product, denoted by , that yields a second-order tensor given by Similarly, the second-order tensors and , or and respectively, have a scalar product given by WebCross product (two vectors) [ edit] Let a positively oriented orthonormal basis of a vector space. If (a1, a2, a3) and (b1, b2, b3) are the coordinates of the vectors a and b in this basis, then their cross product can be written as a determinant: [5] hence also using the Levi-Civita symbol, and more simply:
