Below is a question asked on the forum math.stackexchange.com. Provide a good and informational response to it like a helpful human would. Question: $$\lim_{n\rightarrow \infty}\frac{1}{n^{2}+1}+\frac{2}{n^{2}+2}+…+\frac{n}{n^{2}+n}$$Thanks in advance Now provide the response and nothing else.
HINT: $$\frac{1}{n^2+n}\sum_{k=1}^n(k)\le \sum_{k=1}^n\frac{k}{n^2+k}\le \frac{1}{n^2+1}\sum_{k=1}^n (k)$$ SPOILER ALERT: Scroll over the highlighted area to reveal the solution We can write the limit as$$\lim_{n\to\infty}\sum_{k=1}^n\frac{k}{n^2+k}$$Then, using $n^2+n\ge n^2+k\ge n^2+1$ we have $$\frac{1}{n^2+n}\sum_{...

Below is a question asked on the forum math.stackexchange.com. Provide a good and informational response to it like a helpful human would.

Observe that$$ 0\leq \frac{x^n}{\sqrt{1+x^n}}\leq x^n$$ for all $x\in[0,1]$, hence$$ 0\leq \int_0^1\frac{x^n}{\sqrt{1+x^n}}\;dx\leq \int_0^1x^n\;dx=\frac{1}{n+1}$$for each $n\geq 1$.

Below is a question asked on the forum math.stackexchange.com. Provide a good and informational response to it like a helpful human would. Question: Show that a discrete and compact subset $D \subset \mathbb{C}$ must be finite. Does this conclusion hold if $D$ is just discrete and bounded? How about discrete and clos...
Proof without open covers: Assume that $D$ is not finite, take an infinite sequence of distinct elements in $D$. The Bolzano-Weierstrass theorem (I hope you know this one) states that there is a subsequence , say $A_{n}$ that converges. But this is impossible, because a convergent sequence has a limit $L$ in $D$ (becau...

Yes, you usually can use clang with GCC compiled libraries (and vice versa, use gcc with CLANG compiled libraries), because in fact it is not compilation but linking which is relevant. You might be unlucky and get unpleasant suprises. You could in principle have some dependencies on the version of libstdc++ used to lin...

Question: The C language was used to write UNIX to achieve portability -- the same C language program compiled using different compilers produces different machine instructions. How co...
AMD and Intel processors(*) have a large set of instructions in common, so it is possible for a compiler or assembler to write binary code which runs "the same" on both. However, different processor families even from one manufacturer have their own sets of instructions, usually referred to as "extensions" or whatever....

Unfortunately, that's not possible (at least as I understood by lot of research) directly from Visual Studio IDE and the only possible way for now is using stand-alone profiler.

Best is indeed to use some regexes: ^[\s_]+|[\s_]+$ catches 1 or more white-space characters or underscores either at the very beginning ( ^ ) or at the very end ( $ ) of the string. Note that this also catches new-line characters. Replace them with an empty string. [_\s]+ Again catches 1 or more white-space characters...

You're much better off using the ANSI syntax SELECT * FROM a LEFT OUTER JOIN b ON( a.id = b.id and b.val = 'test' ) You can do the same thing using Oracle's syntax as well but it gets a bit hinkey SELECT * FROM a, b WHERE a.id = b.id(+) AND b.val(+) = 'test' Note that in bot...
