1. [4 + 10 + 4 = 18 points] (a) (i) Let v 1 , v 2 ,..., v p be vectors in R n . Define the set denoted by Span { v 1 , v 2 ,..., v p } . (b) Let v 1 = 1 4 - 2 , v 2 = 5 19 4 , v 3 = 3 8 - 19 . Let W = Span { v 1 , v 2 } . (i) Determine if v 3 is in the subspace W , showing working. Use PART 1 of the MATLAB HANDOUT to check your answer. (ii) Find dim W giving reason. 2. [4 points] Complete the following definition : A set { v 1 , v 2 ,..., v p } in R n is said to be linearly independent if the vector equation has . 3. [5 × 4 = 20 points] Let v 1 = 1 - 3 - 3 , v 2 = - 1 4 1 , v 3 = 0 1 - 2 , v 4 = 0 0 0 , v 5 = 1 2 3 , v 6 = v 1 - 2 v 3 , v 7 = 3 2 1 . Determine which of the following sets of vectors are linearly independent giving reasons. You might find PART 2 of the MATLAB HANDOUT useful. (i)
