Determine whether the following sequences converge, and find the limit of those that converge a) (1+i)n b) 1/n[(1+i)n)] c) 1/n![(1+i)n)] d) 1/(1+i)n e) n/(1+i)n f) n!/(1+i)n
for every n. Prove: If (a) converges, then 11. Let (a.) and (b) be sequences such that a, b, < so does (bn). There are several ways to prove this; at least one doesn't involve Cauchy sequences or e. Be careful though you don't know that () converges so make sure that your method of proof doesn't in fact require (b) to converge.

y, July AM 1. What does it mean for a sequence {a} to converge to a € R? State the definition (-1)+1 What about sequences that don't converge? Read the following proof by contradiction, and then complete Practice Question 6. Claim: {(-1)"} does not converge to any real number a. Proof: Assume that the sequence converges; that is, assume that there is an a E R such that lim,-(-1)" = a. Then, using & = 1, from the definition of...
