(b) Find projviy, the orthogonal projection of y onto v. Also, find the distance between y and projviy. (c) Show that (v, v2} is an orthogonal set but (V1, V2, V3} is not an orthogonal set. (d) Let H=Span{v, V2}. Find the vector in H that is closest to y. (e) Let W= Span{V1, V2, V3}. Find the vectory in W that is closest to y. It is sufficient to give the normal equation corresponding to this problem without solving it.
