I'm a lecturer of mathematics at the University of the South Pacific. My research interests are in algebraic topology and metric geometry.

comment Trigonometry Limit Question
the limit may be $\infty $, $-\infty $, or it may not exist. In fact, the limit of $\frac{1}{\sin x}$ as $x\to 0$ does not exist (and is thus not $\infty $).

comment Category , lie algebras …
(+1) for the answer and (+ million) for: "... more progressive in this regard than many since". Not only in Lie theory but also in other areas some of the more recent books are afraid to present even mildly categorical perspectives.

comment Please give feedback to my answers (sets)
you need to wrap latex between dollar signs (I edited your question a bit so you can see how it's done). As for your solution, think of how you would convince someone the claim is false. Your answer is incorrect.

comment feedback on my answer regarding set intersections.
what seems to confuse you about the answer you gave? it is a correct counter example, but if it is not clear to you, and since you need to explain your answer, maybe it's a good idea that you actually post your explanation as well. That may help you clarify things and will get you better answers.

also, please refrain from posting the question in the title. That is not what titles are for. Also, you need to use latex commands between dollar signs to make things readable. I edited your question a bit so you can see how it's done.

then why did you not tag it as such?

is this a homework question?

comment Logical expression
@user142956 please note that you didn't ask us anything. You just typed your homework question and then your answer to it. What are you asking us then? (I'm guessing you want feedback, so why not explain yourself better (and politely)).

you need to use latex codes if you want your question to be understood. Insert \forall between dollar signs to get $\forall$ etc. I edited your question a bit so you can see how it's done.

there is a typo: $n$ should be $p$.

@John just to note that to make sense of infinite sums a topology suffices, no need for integration.
