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