Problem 1 Let y = (1,-1) and u = (-1,3). NOTE these are vectors. (a) Compute the orthogonal projection of y onto u. (b) Find the distance from y to the line passing through 0 and u. Problem 2 Let y = (-1,4,3) , u1(1,1,1) u2 (-1,3,-2). NOTE: these are vectors Find the closest point to y in the subspace W = span {u1, u2} Solution a).
