H. Practice working with If Then statements: (a) |5 points| Prove the following statement is true: For all non-zero vectors w, v and w in B": If u, v and w are all orthogonal, then {u, v, w} is linearly independent. (b) |5 points| Prove the following statement is false by providing a counterexample: For all vectors u. v and w in E: If u, v, w are linearly independent, then u, v and w are all orthogonal
