Explanation Formula Used: Cauchy Schwarz inequality is | x y | ≤ | x | | y | Prove: Consider an arbitrary element ε . It is given that y is bounded. Thus there exist B such that | y n | = B for all n ≥ N . Now, use Cauchy Schwarz inequality. | x n y n | ≤ | x n | | y n | ≤ | x n | B For each ε > 0 ,
