 Sep 8 comment How to show that $\lim\limits_{x \to \infty} f'(x) = 0$ implies $\lim\limits_{x \to \infty} \frac{f(x)}{x} = 0$? Wow! This really is an immediate consequence of L'Hopital's rule! Thanks for helping me finish my solution!

Aug 9 comment How do I prove the divergence of this series? @Asaf: Hmm, that's a good point. If the original problem was with $\frac{1}{\log log n}$, I guess my solution was overkill.

I'm sorry I didn't find that when I searched for this question. Jun 7 asked How does the parallelogram law imply the existence of an inner product for a given norm? May 27 comment Understanding the Schwarz reflection principle Thanks! That was the statement and construction given by the book, and while I could understand it, I didn't understand why my construction didn't work. May 27 awarded Scholar May 27 comment Understanding the Schwarz reflection principle Thank you! This was exactly my problem! I had assumed that $f(\overline{z})$ was holomorphic because it was a pretty "nice and simple" function. I just started studying complex analysis, so I had the definition of holomorphic memorized without much intution, but I understand the idea a lot better now!
