Problem 8: Suppose e₁,e2, ..., en is an orthonormal basis of V and V₁, V₂...., Un are vectors in V such that ||ez - vj || < √n for each j. Prove that V₁, V2...., Un is a basis of V. (Hint: Suppose there existed a non-trivial linear relation Σ a¡v; = 0. Consider w = Σ;=1 ªjej. Then ||w|| = ||w−0|| = || Σ=1 a; (e;-vj)||. Now try using the triangle and Cauchy-Schwarz inequalities to the last sum and arrive at a contradiction.)
