3. Two n xn matrices A, B are called similar if there exists an invertible n x n matrix S such that A = SBS-1. If A is similar to B, then B is also similar to A, since B = S-1AS. (i) Show that the two 2 x 2 matrices a- (: :). 0 1 0 0 B - (: :) - a 0 0 1 0 %3D are similar. (ii) Consider the two 2 x 2 invertible matrices (: ?) B-(; ) 1 0 A = 1 0 B = 0 1 2 1 Are the matrices similar? (iii) Consider the two 2 × 2 invertible matrices c - (; :). (: :) C = D = 1 Are the matrices similar?
