Do not use binomial theorem for this!! (Real analysis question)
a) Let (sn) be the sequence defined by sn = (1 +1/n)^(n). Prove that sn is an increasing sequence with sn < 3 for all n. Conclude that (sn) is convergent. The limit of (sn) is referred to as e and is used as the base for natural logarithms.
b)Use the result above to find the limit of the sequences: sn = (1 +1/n)^(2n)
c)sn = (1+1/n)^(n-1)
