For other values of $x$, the exact value of $f(x)$ is obtained.  Or am I wrong when I assure that $f(\sqrt2)=0$? Question I use pgfplots with the ultra thick option ans without explicitly giving the domain for the y-axis. It seems that in this case, some part of my graph is &quot;eaten&quot; by the margin: see the picture below to understand what I mean. Is there a way to avoid this?

If both players are very low health and someone plays this card:    Both players could die simultaneously. What happens in Arena when this event occurs? Does it count as a loss for both players? Does it count at all for your Arena record?  Side note: Holy Nova + Auchenai Soulpriest could cause the same scenario. Why does the mirror modifier sometimes give me an overlapping mesh? When I add a mirror modifier it sometimes doesn't mirror correctly, giving me an overlapping mesh. How can I fix this? Singular vs. Plural with Multiple Gerunds as Subject (IE: [Gerund] and [Gerund] are/is [something].) I'm trying to find out whether I should use a singular or plural verb when there are multiple gerunds as the subject of the sentence. For example:  Running the correct course and keeping a steady pace are/is necessary in order to win.  With either one of these by itself, &quot;is&quot; would be correct:  Running the correct course is necessary in order to win. Keeping a steady pace is necessary in  order to win.  With both gerunds combined, I can't seem to figure out whether the verb should stay singular since each phrase is singular, or if it should become plural since there are two connected by &quot;and&quot;. If we just treat the gerunds as regular nouns, then obviously it would become &quot;are&quot;, but I'm not sure if gerunds have the exact same rules as regular nouns. I know that if the sentence was:  Running the correct course and keeping a steady pace are both necessary.  That &quot;are&quot; would be correct, but without the &quot;both&quot; it sounds incorrect to me. Does anyone know the official rule here? Is it possible, on Debian with Klipper running, to have a separate "clipboard stack" for a particular application?  I'd like the text that I copy in application Y not to be shared with all the other applications running.  All the solutions mentioned at  seems like overkill. Why do Windows 10 foreground apps mysteriously launch as background processes? I need to build a function which parses the domain from a URL.  So, with   http://google.com/dhasjkdas/sadsdds/sdda/sdads.html   or  http://www.google.com/dhasjkdas/sadsdds/sdda/sdads.html  it should return google.com  with   http://google.co.uk/dhasjkdas/sadsdds/sdda/sdads.html  it should return google.co.uk. Which one true in First law of thermodynamics:    $Q = \Delta U \pm W = \Delta U \pm p\Delta V$? (where $\Delta U$ is change of internal energy, $W$ work made by system and $Q=cm\Delta T $ heat made by system.)    or $\Delta U= \Delta Q + \Delta W $? (where $\Delta U$ is change of internal energy, $W$ work made by system and $Q=cm\Delta T $ heat made by system.)   First one from one the finnish physics texbook another is from . What are the summary rules for when to use image stabilization and when not to? When I got my DSLR, I took a lot of pics and all of them came excellent, even though I had VR at the "Off" position.   Since those came out so well, I wonder when should I turn VR on, and when I should just leave it off.   I found  which answer this question in detail, but that's too much for me to understand easily. Can someone explain the strict rules in short?  Should I use VR with tripod? When should I use it when I'm not using a tripod, and when should I leave it off? In reading I am not sure if the issue below could have something to do with needing a custom wordpress ajax handler? All of these functions are inside my functions.php file. I have a couple of PHP functions that are supposed to pass information from one to another. The an AJAX call to the final function should produce the final result through that call. Its not happening. My count results in 0 and I am not understanding why. If I replace my query with a static array like [44,55,99,33] then it will pass the values ok. Likewise if I keep the query and simply replace the $id in the query and make it a static id such as '20' then it works. I would think that the id was the issue then and it wasnt pulling properly but it seems to work ok just not pass? function idx(){     global $wpdb, $id;       $getId = $_SERVER['REQUEST_URI'];     $ecp = explode('/', $getId);     if($ecp[3] != ''){         $id = $ecp[3];     }         return $id; } add_action( 'after_setup_theme', 'idx' );  =============================================== function Total_Result(){     global $wpdb;     $id = idx();        /*$resultx = [44,88,59,52];*/ ;      $resultx = $wpdb-&gt;get_results( $wpdb-&gt;prepare(&quot;SELECT * FROM {$wpdb-&gt;prefix}custom_form_submission_conversation as cc LEFT JOIN {$wpdb-&gt;prefix}custom_form_submission as cs on cc.fsid ='$id' WHERE fsid='$id'&quot; ));          $resultxs = array($resultx);          $total_result =  count($resultxs[0]);     echo  $total_result; }  when I var_dump $resultx I get: array(3) { [0]=&gt; object(stdClass)#1256 (36) { [“cid”]=&gt; string(3) “167” [“fsid”]=&gt; string(2) “20” [“specified_date”]=&gt; string(3) “yes” [“price_quote”]=&gt; string(4) “1140” [“posted_by”]=&gt; string(9) “dc_vendor” [“limit_count”]=&gt; string(1) “1” [“read_unread”]=&gt; string(1) “1” [“vendor_response”]=&gt; string(4) “zero” [“date_created”]=&gt; string(19) “2021-04-15 11:39:08” }   [1]=&gt; object(stdClass)#1257 (36) { [“cid”]=&gt; string(3) “186” [“fsid”]=&gt; string(2) “20” [“specified_date”]=&gt; string(3) “Yes” [“price_quote”]=&gt; string(3) “602” [“posted_by”]=&gt; string(8) “customer” [“limit_count”]=&gt; string(1) “1” [“read_unread”]=&gt; string(1) “1” [“vendor_response”]=&gt; string(4) “zero” [“date_created”]=&gt; string(19) “2021-04-15 11:39:08” }   [2]=&gt; object(stdClass)#1258 (36) { [“cid”]=&gt; string(3) “188” [“fsid”]=&gt; string(2) “20” [“specified_date”]=&gt; string(3) “yes” [“price_quote”]=&gt; string(4) “1017” [“posted_by”]=&gt; string(9) “dc_vendor” [“limit_count”]=&gt; string(1) “1” [“read_unread”]=&gt; string(1) “0” [“vendor_response”]=&gt; string(4) “zero” [“date_created”]=&gt; string(19) “2021-04-15 11:39:08” } }   so then I try and pass that data like so: function getvendorresponsestatus() {     global $wpdb; $id = idx();          $total_resultx = Total_Result($id);         die; }  Ive tried with and without the die();. The AJAX call is: setInterval(function(){     var ffiidd = jQuery('#ffiidd').val();     var ajaxurl = &quot;&lt;?php echo admin_url('admin-ajax.php'); ?&gt;&quot;;          jQuery.post(ajaxurl, {         action: &quot;vendorAjaxprog&quot;,         ffiidd: ffiidd     }, function(data) {         console.log(data);         jQuery.post(ajaxurl, {             action: &quot;getvendorresponsestatus&quot;, //&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt; this is the action that calls the function             fsid : ffiidd         },         function(datas) {             console.log('+ datas);             jQuery('.cust_vendor_top').html(datas);         });         if(data == 0){}else{             jQuery('.ajaxreload').html(data);                                     }     });               }, 5000);/*==30 seconds==*/  So the question is why wont it pass along the query array information but it passes a basic array or it will pass if I change the id in the query to be static? I know the query is good because of when I var_dumped it, I have results before I get to the Total_Result() function. I understand that the output voltage is determined by the ratio between the two resistor values, and that if the both resistors are same then output voltage will be exactly same for all; but what's the basis of picking the resistor values?there is any need of consider output current to choose resistor value. Does the Symmetric difference operator define a group on the powerset of a set? $G$ is the set of all subsets of a set $A$, under the operation of $\triangle\;$: Symmetric Difference of sets.  $A$ has at least two different elements.  I need to check if this is a group, and if it does to show if the group is abelian and/or finite.  Associativity - easy from Symmetric Difference. Identity element - empty group. Inverse element - each element is inverse to itself. Am I right?  abelian? finite? Find and replace text within multiple files Why does Java's hashCode() in String use 31 as a multiplier? Per the Java documentation, the  for a String object is computed as:   s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1]       using int arithmetic, where s[i] is the    ith character of the string, n is the length of    the string, and ^ indicates exponentiation.   Why is 31 used as a multiplier?  I understand that the multiplier should be a relatively large prime number. So why not 29, or 37, or even 97? LuaLaTeX, TeXLive 2016, standalone: undefined control sequence Send file using POST from a Python script something like wye-delta and delta-wye connection.  we can originally know wye-delta connection is step-down transformer and second side voltage phase is being to -30 degree. And also delta-wye connection is step-up transformer and second side voltage phase is being to +30 degree.  But the other side, we also can make wye-delta connection is step-up transformer if it get turn ratio like 1:2. So in this case maybe will be become +30 degree in second side voltage.   apply this principle in scott connection, how can work it?   case1) turn ration 1:2 - step up second side voltage's angle +90 degree?  case2) turn ration 2:1 - step down second side voltage's angle -90 degree?  if you have any information or homepage link, can you leave it for me?  thank you so much.
