6. (10) Show that if W is a k-dimensional subspace of an inner product space V (not necessarily finite dimensional), then b - projwb is perpendicular to every vector in W. Here projwb is the orthogonal projection of b onto W. (Hint: Use the theorem that W has an orthonormal basis (a, a, .., ak), show that (b - projwbla) = 0, for all :)

Why does this show that H is a subspace of R3? O A. The vector v spans both H and R3, making H a subspace of R3. OB. The span of any subset of R3 is equal to R3, which makes it a vector space. OC. It shows that H is closed under scalar multiplication, which is all that is required for a subset to be a vector space. OD. For any set of vectors in R3, the span of...

Show that VH = {y ∈ C∞ | D[y] = 0} is a subspace for any linear differential operator D. (C∞ is the vector space of all functions with infinitely many derivatives to ensure that we have a vector space to inherit addition and scalar multiplication.)
