It's very important to have a feeling for how sequences compare with each other.

Let's write:

	{an} >> {bn}	if     (an/bn) -> +   as n ->
and	{an} << {bn}	if     (an/bn) -> 0       as n ->

(Think of >> as "infinitely bigger in the limit"
and << as "infinitely smaller in the limit")


Problem: Line up the following sequences, deciding which is "first", "second", "third", etc so that:

first  <<  second  <<  third  <<  fourth  <<  fifth  <<  sixth

a) (n)

b) en

c) n!

d) n2

e) ln n

f) nn
