comment Prove that every irrational numbers can be approximated by rational numbers.
If you want to split hairs, it doesn't mean that reals can be approximated by rational, since with this definition they don't live in the same set. You still have to talk about the identification of $ℚ$ with a certain dense set of $ℝ$.

revised A function $F:\mathbb{Q} \rightarrow \rm numerators$
I now know it used to be the common notation, but it confused the hell out of me at first, and I am probably not the only one

comment Is there such a thing as a removable singularity for a power series on the edge of the convergence disc?
@GerryMyerson Ah, is this called “removable singularity”, too? Then I suppose you have it right. There are different word for this and complex analysis singularities in French.

@GerryMyerson Well, I know that, it is the point of this question. What could removable singularity mean in this context?
