Interested in Joining a Real Analysis Study Group Online?
Yes, I am interested. I have taken two semesters of advanced caculus and one semester of Real analysis. I have several books related to Real analysis but I suppose buying a new one wouldn't hurt.

Is It Possible to Embed the Set of Rational Numbers in a Countable Set?
What about the H. L. Royden method of showing countability, showing that the set is the range of a sequence?

Is It Possible to Embed the Set of Rational Numbers in a Countable Set?
What about f(1, 2) and f(2, 4)? I don't think f is one-to-one.
