The study of such equations is not "abstract algebra" as it is usually understood.

This is in marked contrast to the case of integer...

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: Assume I have formulas $H$, $P$ and $Q$.

If $H$ is consistent then yes. Assume towards contradiction that this is not the case, then $P\vdash Q$. $P\vdash Q$ implies $\vdash P\rightarrow Q$ using the deduction theorem. Therefore $H\vdash P\land P\rightarrow Q$. And so $H\vdash Q$. If $H$ is inconsistent (e.g. $0=1$ or $\varnothing\in\varnothing$ sort of thing...

Hint: You want to demonstrate - $9<\sqrt{89}<10$ What happens when you square across these terms? This can be done because, based on the suggested edit by Cameron Buie, each term can be squared for an equivalent chain of inequalities since $x↦x^2$ is a strictly increasing function on the positive reals.

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: Is there any necessary and sufficient condition to determine whether a subset $H$ of a given field $K$ is a subfield? In some paper I have found something like that: $H...
The statement is false as written, since you could have $b=0$. A subset $H$ of $K$ is a subfield if and only if $H$ is a subgroup of $K$ under addition, and the nonzero elements of $H$ are a subgroup of the multiplicative group of nonzero elements of $K$. Thus, $H\subseteq K$ is a subfield of $K$ if and only if: $H\neq...

The style looks fine to me. Although the Sieve of Eratosthenes is a very efficient way to find prime numbers, your approach works well too, since you are only testing for division against known primes.

You don't really "add" the complexities. Sorting is, as you say, O(n * log n), and searching is O(log n). If you were to do "normal math" on them, then it would be (n+1)*log n, which is still n*log n. When you're performing multiple steps like that, you typically take the highest complexity and call it that. After all,...

Boosting can generally be understood as (weighted) voting In the case of boosting, one of its inventors gives an affirmative answer in this introduction to AdaBoost (emphasis mine): The final or combined hypothesis $H$ computes the sign of a weighted combination of weak hypotheses $$F(x) = \sum_{t=1}^T\alpha_th_t(x)$...

This is overkill. all you need is: src/main/res This is your common resources for all your flavors src/dev/res This is the resources specific to the dev flavor. src/prod/res This is the resources specific to the prod flavor. etc...

Bundles! The workflow with git bundle is going to be essentially the same as any other workflow. This may not seem like terribly helpful advice, but here it is: use whatever workflow you would normally use, and replace "push/pull" with "carry a bundle here to there on a flash drive, then pull". The man page actually ha...

customize-set-variable is what you want, not custom-set-variables (no need for that here). And in general it is a good idea to also take a look at the defcustom for the variable (user option), to see what its :set slot does etc. Not necessary, but good to know before you try to set the value programmatically. This repl...

Question: There is already a thread about Detecting WebP support using client-side. How to detect WebP support using server side? Now provide the response and nothing else.
Today, you should check the accept header for image/webp . All browsers which support WebP will send this as part of their accept string for all requests (images and non-images). In short: if( strpos( $_SERVER['HTTP_ACCEPT'], 'image/webp' ) !== false ) { // webp is supported!} (you might want to use preg_match inste...

Suppose $\exists n\in\Bbb N$ such that $n=\sum_{i\in A}2^i=\sum_{i\in B}2^i$ with $A,B\subset\Bbb N_0$ . Then $\sum_{i\in A}2^i-\sum_{i\in B}2^i=0$ and so for set $C=A\Delta B$ (symmetric difference) and some function $s:C\rightarrow\{-1,1\}$ we have $\sum_{i\in C}s(i)2^i=0$ . Now if $C\ne\emptyset$ then $C$ has a larg...
