We will prove the Cauchy-Schwarz inequality for infinite series. Let (a,) and (bm) be two sequences such that a and E both converge. (a) Give an example a sequence (a„) where Ea, diverges but E¢ converges. (b) Use induction to show that for any N > 0 N This is the Cauchy-Schwarz inequality for finite sums (or the dot products). (c) Show the (Ena)" (E«) (E•) Σ This is the Cauchy-Schwarz inequality for infinite sums. (d) Why does part (c) imply that ab, converges?
