Jeremy. Well, one reason is that two quantities could both approach infinity, but not at the same rate. For example imagine the limit of (n+1)/n^2 as n approaches infinity. Both the numerator and the denominator approach infinity, but the denominator approaches infinity much faster than the numerator. So take a very large n, like 1 trillion.
