Aside from the Milky Way, what are the most studied galaxies in the universe? Why are they focused on over other galaxies?
The Andromeda Galaxy, Triangulum Galaxy, Large Magellanic and Small Magellanic Cloud are the most studied galaxies. That's because they're very close to us and not too far away. Some satellite galaxies of Milky Way are studied as well,

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
