Unformatted text preview: counterexample. 4. Consider the following matrix: A = 1 2-1 4 2 0 1 2-2 0 0 1-1 0 0 3 4 5 1 0 1 2 3 (a) Compute the determinant of A . Hint: The computations become more manageable by expanding the determinant in an appropriate way. (b) Suppose you wanted to enter the matrix A in MATLAB. Consider starting with the zero matrix of the right size: A = zeros(5,5) Write the MATLAB commands that would enter the two non-zero rows in the third row of A . 5. Let T : R 2 R 2 be the linear transformation that corresponds to the orthogonal projection to a unit vector a making an angle of = 60 degrees with respect to the x-axis. Find the determinant of the matrix representing T ....
