ASSIGNMENT 6 EE441 KUMAR Fall 2007 Due: Monday, Oct. 15 1. Find a basis each for the rowspace, columnspace and nullspace of the matrix A = 1 2 0 - 1 1 3 1 1 2 5 1 0 3 6 0 0 . 2. What is the coordinate representation of the vector [1 0 0] T with respect to the basis A = n [1 2 3] T , [0 1 2] T , [0 0 1] T o ? 3. Consider the following two basis for < 2 : A = (" 1 2 # , " 3 4 #) and B = (" 1 1 # , " 1 2 #) Find a matrix P such that [ x ] B = P [ x ] A for all x ∈ < 2 . 4. What is the dimension of the vector space of all 3 × 3 upper triangular matrices ? (A is upper triangular if and only if a 21 = a 31 = a 32 = 0). 5. If the n columns of an n × n matrix A are linearly dependent, the same will always be true of the n columns of the matrix A 2 . (i) True (ii) False
