1. Consider the foowing three vectors u, v, W in a 6dimensional space: u: [1,U.25,U,U,U.5,0] v: [0.?5,0,U,0.2,U.4,U] w : [U,0.l,U.?5,U,U, 1] Suppose we construct 3bit sketches of the vectors by the random hyperplane method, using the randomly generated normal vectors r1, IE, and r3, in that order: r1: [1, 1, 1,1, 1, 1] r2 : [1,1, l, 1, 1, 1] r3 : [1, 1,1, 1,1, 1]
