Unformatted text preview: A is not invertible. SOLUTION Write A in the form A = [ v 1 , v 2 , v 3 ]. Then the given information is that v 1v 2 = v 3 . This is the same as v 1v 2v 3 = 0, and this is the same as [ v 1 , v 2 , v 3 ] 111 = 0. Hence there is a non zero vector v with A v = 0, and this means that A is not invertible. 3.25 (a) Show that h 1 1 /n 1 i n is the same matrix for all values of n .
