Unformatted text preview: A = 0 . So we need to show that A = 0 . We are given that for all Î» âˆˆ C â‰¤ B2 Re ( Î»A ) We prove that A = 0 by contradiction. Assume that A 6 = 0 . Taking Î» = B/ A yields that â‰¤ B2 Re Â± B A A Â² =B which contradicts the assumption that B â‰¥ . Therefore A = 0 . which completes the proof. 7. See problem 21 Sec 1.1...
