Consider the square 3 x 3 matrix [mi whose elements mij are generated by the expression m 1.1. = ij2 forc, j = 1,2,3, and a vector v whose components in some basis are given by vk = k fork = 1,2,3. [u, (a) using a matrix representation for -+ determine the components of the vector that result from a premultiplication of by [mi. [u (b) determine the components of the vector that result from a premultiplication of [mi by [ut.
