TL;DR: The Community Team has been doing discovery work on the possible creation of new community roles across the Stack Exchange network and individual sites. We started by approaching site moderators, and now we want to hear from the broader community about different roles you would like to se...
A clear duplicate IMO: math.stackexchange.com/q/4587206/42969. In the suggested dup target it is explained why an equation can not be solved by differentiating both sides of the equation. Also one of the answers does not answer the posed question at all.
@amWhy That's a puzzling claim. Surely if someone wanted to avoid having others "weigh in" then they would not post deletion (and closure) requests here. Imo using your GB to reopen a dupe (of a FAQ) in order to prevent deletion (needed only 1 vote) is an abuse of GB power. All the effort involved in organizing that dupe has now been destroyed by a single click (by a user who has no demonstrated expertise in teaching the topic at hand). This is highly disturbing.
@Peter Such comments can be flagged as “no longer needed (outdated, conversational or not relevant to this post).” – Already done here, and quickly handled by a moderator.
If you see a pattern of repeated such comments from the same user then a custom moderator flag might be appropriate.
@amWhy Thanks for the background, and the greeting. Personally I'm fine (even though I finally caught COVID), but Europe has certainly changed due to the war. And my savings have taken a bit of punishment. Luckily not too severe - like instead of €100 bottles of single malt I may need to go back to €60 bottles :-)
Suppose $f \in L^{p_0} \cap L^{\infty}$ for some $p_0 < \infty$.
Prove that:
$\lim_{p \rightarrow \infty} \|f\|_p=\|f\|_{\infty}$
My attempt:
So the first step seems to be showing that the limit exists at all. I'm having trouble showing this, I feel like I'm getting a massive case of tunnel ...
@postmortes I'm afraid. I'm probably missing something. OP says-"In a space of measure 1, $\|f\|_p$ is increasing ...". And as noted in the comments, the general case seems to be missing in the post (including both the answers as well).
