Anyone who can help me with this?

1 5. Consider the iterative improvement algorithm discussed in lecture Solve Ax = b for initial approximation io. for i = 0, 1, . . . until convergence compute ri = b-Ari solve Azi = ri update zi+1 = a, + end for We gave an intuitive explanation of why this algorithm could improve the initial approximate solution ro, but we were vague on the conditions required for convergence. In this question, you will attempt to derive the precise conditions required for convergence Page 2 of 3 pages
