+HW4 Questions:
+. What does it mean to "realize" limsup as sup by supS = limsup + ε?
+. Why does the ratio test only require that limsup < 1, not that the ratio converges?
+. Is there a simpler technique for proving lim(an bn) = lim(an) lim(bn)? specifically with the inequalities, I found those confusing
+. Do we ever have to apply the Dedekind cut in our proofs? Or was that just a construction to get us started with the reals?
+. I understand that the rationals are countable, but what order is their enumeration? Does it matter?
