Why does $\int_1^\infty \sin(x\log x)\,dx$ converge?  I haven't got a clue about where to being with this, any help would be appreciated.
I tried a couple of substitutions but have so far gotten nowhere. Can anyone guide me in the right direction? Thanks for your time.
How to generate multiple maps where one highlighted attribute changes? I have a layer that contains counties within the state of Washington.    I need to build one map (jpg) for each county.  For that specific map all counties will show as light grey, but the specific county will be green, and the file name will be the county name. I want to create this:  Note that wire lay chaotically, so spiral object not the same thing.  There is a cool way to do this task in 3ds max:  Basically he deform straight spline/curve and then bend it couple iterations (over 9000 degrees angle in max).   Blender can't bend that way with simple deform as I know, only up to 360 degree. Is there any other way to make wire wrapping similar to photo? In comics does Batman have a rule against killing? Inspired by  question, I have to admit I don't know a lot about the Comic Book Batman, but I know a fair amount about his other incarnations.   I know for example, that the 1989 movie had him kill the Joker. He vehemently wanted the Joker dead and had no compunctions about taking a life. I also know that he had a rule against killing in The Animated Series that he never broke, and that he very nearly broke it in Batman Beyond.  But as far as the comic books go, when did Batman develop a rule against killing his foes? Does he ever kill them rather than deliver them to the proper authorities? "Pending" vs "Impending". Are they synonyms? They appear to me to mean almost if not exactly the same thing, but I am not sure. Are there differences in meaning between them? In how many different ways can we place $8$ identical rooks on a chess board so that no two of them attack each other? In how many different ways can we place $8$ identical rooks on a chess board so that no two of them attack each other?  I tried to draw diagrams onto a $8\times8$ square but I'm only getting $16$ ways.  Does that sound right?  Thanks for the help! When I try to play multiplayer I type in the only server I know, which the game says was right, then click Play and it loads. Then it says Can't connect to server: bad log in. How can I fix this? Big Parenthesis in an Equation I have an equation contained inside \[...\], which automatically makes a \sum with sub- and superscripts turn big--so that the summation sign looks awkward inside parenthesis.  Any idea how to make the parenthesis completely enclose the whole summation?  \documentclass{article} \begin{document} We have: \[ \sum_{i=1}^n i = (\sum_{i=1}^{n-1} i) + n = \frac{(n-1)(n)}{2} + n = \frac{n(n+1)}{2} \] \end{document} How do I fill arrays in Java? I know how to do it normally, but I could swear that you could fill out out like a[0] = {0,0,0,0}; How do you do it that way? I did try Google, but I didn't get anything helpful. How to import a .max model into Blender? Is it possible to retrieve a previous un-evaluated, un-normalized input? Why is everybody so concerned about etc/passwd? Office 2016 Advanced Setup I just started the Office 2016 Setup/Installation on my Windows 10 PC. The installation worked fine and started automatically showing only this dialog:    But there are no additional settings possible! I need to choose which programs I want to install and also add additional tools that are often missing when doing a default installation.  How can I change the Office Installation Settings?   Choose programs to install Add/Remove Office Tools (Maybe) Office installation directory   When I check after the installation in the the windows settings, the Office can only be uninstalled - no modifications available: I would like to try a different video display driver, but I'm not sure which one I'm currently using.    What's the simple way to see what driver my system is using currently? We often see new users make offtopic, low quality posts, with broken English and cries for help. These questions look significantly different from most on SO.  When I worked in publishing, we would frequently receive documents that were incorrectly formatted. This was a major problem and we wasted a lot of time sending emails back and forth.  I made a small JavaScript quiz asking our authors about the formatting directions and the number of emails drastically dropped. I felt this was much nicer than simply rejecting them, additionally providing us a chance to make the directions more clear.  It is slightly unconventional but, would showing new users a quiz where they have to identify good and bad posts help to improve the quality of SO questions?  Edit (3/8/2017)  Recently a Norwegian website got some media attention for . Let's say I write a mine.service file. Then I use systemctl enable mine.service.  If I later decide to edit mine.service, do I have to tell systemd that mine.service was changed? If so, how do I do that? Cannot get grub menu to timeout (or go away) I am running Ubuntu 12.04.  I cannot for the life of me get the grub menu (with options) to go away.  I would like it to auto-boot into the first option. I've edited /etc/default/grub so that it looks like the following:  GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2&gt; /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=""   After this, I ran sudo update-grub. Then I realized that I had grub 2, so I ran sudo update-grub2 (both make it look like they create the grub.cfg file successfully.  I restart my computer and it goes back to the grub menu and just sits there until I make a choice. This is not desirable if the power goes out... :-)  I also tried reinstalling grub using sudo grub-install /dev/sda - also unsuccessful Wanted: question mark instead of bibtex key for missing citations (biblatex) Instead of having the citation key showing up in the document for missing references, I want to only have [?], as it is the case when using the default bibtex without biblatex. This behavior is driving me crazy, as it messes up all the formatting (especially in tables). I want to focus on writing and only later on deal with the erroneous citations.  This question is related to    and its MWE can be used. However, as pointed out beforehand, I want the question mark in the text instead of the citation key to not mess up the formatting (for missing citations). Why does WCF return myObject[] instead of List like I was expecting? If I have $f:\mathbb{R}\rightarrow\mathbb{R}$ such that $f$ is onto and $f\circ f\circ f = f$, how can I prove that $f$ is bijective? I know that I only have to prove that it is 1-to-1 because I'm given the fact that it's onto, but how can I use the fact that $f\circ f\circ f=f$ to prove that it is 1-to-1?  Thanks! How quickly does the Ultimate Meter fill up? The information on the :     Ultimate abilities are powerful abilities only available to a hero   once their Ultimate Meter has filled. Progress towards an Ultimate   persists through death. The Ultimate Meter fills by killing/dealing   damage to enemy heroes, though Mercy gradually fills hers through   healing with her Caduceus Staff, and Torbjörn's turret generates   Ultimate progress for him. The amount of Ultimate gained appears to   vary between heroes, and kills seem to grant less Ultimate than   dealing damage.   Nowhere does it explain how quickly the meter is gained, and what % of meter corresponds to damage.  I know that in addition to that, meter is also passively gained for all heroes, albeit very slowly. What is the rate of that passive Ultimate meter? How does damage correspond to ultimate meter %?
