Problem #5: (a) Let u =(2, -4,-8, -10) and v=(-1, -3, 8, -10). Find ||u – proj,u||. Note: You can partially check your work by first calculating projyu, and then verifying that the vectors projyu and u-proj,u are orthogonal. (b) Consider the following vectors u, v, w, and z (which you can copy and paste directly into Matlab). v = (-8.1 4.2 6.3], w = [-9 -3.7 5.5], u z = = [-8.6 -3.4 -7.1], [-3.2 2 -4.9] Find the...
