Let W be a subspace of Rn. Prove that W n WL = {0}. Identify the error(s) in the following proof: (Select all that apply:) wL is defined to be the set of all vectors in Rn that are orthogonal to every vector in W. Assume that W 0 WL {0}. Ifw ewn wL then w = 0. But this means that w 0. Thus 0 is only element of W n WL. We cannot assume W n WL = {0}_ WL is defined to be the set of all vectors in B" that are orthogonal to some vectors in W, not every vector. We cannot say w eWn WL U w = 0 does not imply w = 0
