comment why symmetric matrices are diagonalizable?
@Ted thank you for this! I meant to use normality rather than symmetry. I made the corrections. Thanks!

comment Stategy for prime factorization
That is an interesting comment @RobertIsrael. I would suspect most algorithms will not directly use division on the given number they factorize, but that they still use plenty of divisions. But I'm not really well-versed in state-of-the-art factoring algorithms.

comment $1^\infty=1$ or is indeterminate?
@marcelolpjunior that was not what the question stated. You asked about $1^\infty $, not about $\lim _{x\to \infty }f(x)^{g(x)}$ where $\lim_{x\to \infty }f(x)=1$ and $\lim_{x\to \infty }g(x)=\infty $. As I said in my question, it's one to you to define what $1^\infty $ means. You now changed its meaning from what I described in my answer. So, you get a different result.

comment What newer mathematics fields helped to solve or solved problems from older fields of mathematics?
@MartinBrandenburg I'm really not qualified to explain what Shelah's classification theory is all about. I can't recall now specific problems in group theory solved by Shelah, but there is a long list of such problems in Chang and Keisler's "Model Theory".

revised How can I show that a sequence of regular polygons with $n$ sides becomes more and more like a circle as $n \to \infty$?

Welcome to SE. Please note that when you ask homework questions you should tag them as such and that you are expected to show some effort. Tell us what is not clear, or where you got stuck, instead of just commanding us to solve something. And explain why.
