Math 136 Tutorial 4 Problems 1: Let A = 12 3 - 1 21 , B = ± 31 - 1 - 1 ² , C = ± 3 4 ² . Calculate the following or state that they don’t exist: a) AB b) CB c) C T A T . 2: Let S = { (1 , 1 , - 1) , (0 , 1 , - 1) , (2 , - 1 , 1) , ( - 1 , 2 , 3) } . a) Write the system of linear equations we would need to solve if we wanted to determine if S is linearly independent or dependent. b) Just by looking at the system of linear equations, how can you tell that S must be linearly dependent? c) By solving the system, Fnd two linear combinations of the vectors in
