Rules governing examinations: each candidate must be prepared to produce, upon request, a. Part a - short answer questions, 1 mark each. For questions a1-a3 below, x and y are the vectors given below: x = [1, 1, 1] y = [1, 1, 2] A5: if 2 and 3 are both eigenvalues of a 2 2 matrix a then a must be invertible. A6: for what values of the parameter a does the matrix. A7: find the inverse of the matrix (cid:20) 1 2. For questions a9-a11 below consider the circuit in the diagram below: A9: list the unknowns in the linear system for this circuit set up using the techniques you learned in the computer labs this term.
