I was wondering if I could ask for references for a particular type of questions from MSE. Is it legal?
For example, if I wanted references of questions which were related to proving $\lim_{n\rightarrow \infty} \frac{a^n}{n!}=0$. (I had come across quite a lot of such types.)
There are many questions (a few of them [duplicate]s) that answer the question. But when we look at the answers to all those questions, we get to understand the different approaches to the same question. With every new answer to such type of question, we get to know something new. Sometimes these questions are not marked as duplicates due to slight change in the phrasing or different questions with exactly the same underlying concepts.
