This assignment asks you to prove the following Proposition 1 Let {n} and {n} are two sequences of real numbers and L is a number such that (1.a) un → 0, and (1.b) V EN, -L Swn. We illustrate the proposition. To begin, one can check from the definition that 1/n 0. This fact, plus the arithinetic rules of convergence, generate a large family of sequences known to converge to 0. For example, 11n +7 1 11 +7 3n2 -...
