In Cartesian coordinates, a rank-2 tensor is given by [ = [xxexx + Exzexz + Tyyeyy and a Cartesian vector is n = nxex + nyly Note that the scalar coefficients of the "missing" elements of I and n are all 0. Evaluate: a) . n b) n't c)nn d) ixn 22 e) Be sure to explicitly include base vectors and base dyads when appropriate
