: 1 Assume That U1 U2 U3 U4 Is An Orthogonal Basis For For R4 Where U1 1 2 1 1 U2 2 1 1 1 Uz 1 1 2 1 (50.5 KiB) Viewed 27 times

1. Assume that {U1, U2, U3, U4} is an orthogonal basis for for R4, where U1 = (1,2,1,1), U2 = (-2,1,-1,1), uz = (1,1, -2, -1), 44 = (-1,1,1,-2) and x = - = > Using theorem 5, write x as a linear combination of U1, U2, U3, U4. DO NOT DO ROW REDUCTION!
