Now consider A, x, b, where n is not specified. Put (1) into the form Ux = c, where U is upper triangular using Gaussian elimination (you do not have write what c is since b is not given). What is maxi, j |ui, j |? (d) For large n, e. g. n = 2000, what problems can you envision if you try to solve (1) using Gaussian elimination on a computer? Explain.
