4 Using the Einstein summation convention, show explicitly that (a) a. bxc = axb.c, where a, b, and c are arbitrary vectors; [2] (b) V(a a) = 2ax (V × a) +2 (a. V) a, where a is a vector field. [3] 5 (a) Give the definition of the second-rank pseudo-tensor. [2] (b) Let Aj be components of a matrix representation of a second-rank tensor A in a particular Cartesian coordinate frame. Demonstrate that det(A) is invariant under rotation of the coordinate axes. [3]
