comment When a function contains a sequence, and how to find the function's limit?
@ElleryLai Do not intend to exhaust all cases to be analyzed. In the case of home work, is not purpose of this site provide full answers.

comment When a function contains a sequence, and how to find the function's limit?
@Ellery If $\lim_{n\to \infty}\frac{n}{x\cdot a_n}=L\neq 0$ and $L\in\mathbb{R}$ then the question is trivial. In your secont coment you are right. I hope helped you.

comment Proof of Banach's homeomorphism theorem without the contraction map principle.
@UmbertoP. Yes. There is. But speaking in terms of mathematics fundamentals I do not believe that such a test would find walking through results that were independent of Banach's fixed point theorem or domain invariance theorem. I think I could proof that uses connectness. I am writing a review about the implicit function theorem. Indeed an alternative proof that does not use the Banach's fixed point theorem.

@Siminore No. I had not seen this issue in MathOverflow. The answer ultimately lead me to references I've consulted. Thanks anyway. +1.
