What is the LaTex command for common notation for time scale as shown in picture?

I know what my symbol or character looks like, but I don't know what the command is or which math alphabet it came from. How do I go about finding this out?

A number of related questions have already been asked about this issue:       and even    But I'm still confused by the conflicting suggestions that have been given so far. So I'm trying again.  Which should be the preferred command to produce a displayed equation in my LaTeX documents?  So far the suggestions indicate that one should use \[ ... \], maybe \begin{equation*} ... \end{equation*}, or maybe even the gather* or align* environments from amsmath.  And one should definitely avoid using either $$...$$ or the eqnarray environment.  Now I have to say that, from a language perspective, I have a strong preference for the equation* environment because it is less cryptic than the \[ ... \] notation and it is  the most accurate.  So, is it fine to use equation*? Maybe only after loading amsmath? Or should the equation/equation* environment be redefined to something else so that spacing, package support, or whatever is improved?

I can output the value of a counter in a LaTeX document via:  \setcounter{mycounter}{1} \arabic{mycounter}   Which inserts a 1. But how do I format the output by, for example, adding a leading zero if mycounter is less than 10 in a way similar to what  lets you do by specifying %02d as your format string?

LaTeX commands like this:  Here again, four different simulations are run on networks of size  $C^{G} = 25 \times\ 25 = 625$, $C^{G} = 50 \times\ 50 = 2500$, $C^{G} = 250 \times\ 250 = 62500$, and $C^{G} = 500 \times\ 500 = 250000$...   When compiled generate the following:    The spacing in math mode really irritates me. There's too much white space around the equal sign, and the multiplication sign has more right padding than left padding. Is there any way to reduce this spacing?

This is primarily for Windows 7, but I work in multiple versions and would happy to be able to do it in as many of them as possible.  Currently, when I open Explorer and look at a list of files, the date modified column shows something like:  09/18/2013 10:03  I would like it to display:  09/18/2013 10:03:42  I've tried changing the region and language settings for the short time format from HH:mm to HH:mm:ss, but it says it ignores seconds for that.  Does that mean I'm just out of luck?  And again, I'd like to be able to do this in any other  previous versions of Windows too.  It's useful for me as a developer to be able to see the seconds in a lot of situations.  Minor clarification: I did find , which helped me to improve the file properties display, but I wanted to be able to view the full timestamp for all the files in a folder at once, instead of individually.

Does latex do anything special with periods?  If so, is there a way to differentiate end-of-sentence periods from periods indicating abbreviation?

I'm trying, but something is wrong with my code in LaTeX: \begin{asy} pair dynkinMark(real x, real y, string s = &quot;&quot;, pen p = defaultpen, pair B = dir(45)) { if (s != &quot;&quot;) { dot(&quot;$&quot;+s+&quot;$&quot;, (x,y), B, p); }     else { dot((x,y), p); }     return (x,y); }  dynkinMark(0,1, &quot;1&quot;, dir(135)); dynkinMark(0,2, &quot;2&quot;, dir(135)); dynkinMark(0,3, &quot;3&quot;, dir(135)); dynkinMark(0,4, &quot;4&quot;, dir(135)); dynkinMark(7,1, &quot;1'&quot;); dynkinMark(7,2, &quot;2'&quot;); dynkinMark(7,3, &quot;3'&quot;); dynkinMark(7,4, &quot;4'&quot;); path p1 = (0,1)..(2,2.0)..(5,3.5)..(7,4); path p2 = (0,2)..(2,1.2)..(5,2.5)..(7,3); path p3 = (0,3)..(2,2.8)..(5,1.5)..(7,1); path p4 = (0,4)..(2,3.8)..(5,3.5)..(7,2); draw(p1, blue); draw(p2, heavycyan); draw(p3, mediumcyan); draw(p4, lightblue); dot(&quot;$12$&quot;, IP(p1, p2), dir(90), heavygreen); dot(&quot;$13$&quot;, IP(p1, p3), dir(90), heavygreen); dot(&quot;$23$&quot;, IP(p2, p3), dir(90), heavygreen); dot(&quot;$14$&quot;, IP(p1, p4), dir(90), heavygreen); dot(&quot;$24$&quot;, IP(p2, p4), dir(90), heavygreen); real y = 0.8; label(&quot;$s_1$&quot;, (IP(p1,p2).x, y), heavygreen); label(&quot;$s_2$&quot;, (IP(p1,p3).x, y), heavygreen); label(&quot;$s_1$&quot;, (IP(p2,p3).x, y), heavygreen); label(&quot;$s_3$&quot;, (IP(p1,p4).x, y), heavygreen); label(&quot;$s_2$&quot;, (IP(p2,p4).x, y), heavygreen); \end{asy}

I looked "$\divideontimes$" up on Google and now I know that it's Unicode U+22c7 but when would it be used?  I am guessing that $5 \divideontimes 5 = 25$ and $1$...?

Recently in some LaTeX documentation I noticed that there is a special LaTeX command for the symbol meaning "corresponds to", which is similar to an equal sign with a hat on top. \hat{=} or \widehat{=} both do not give satisfying results (my personal view). Unfortunately, I cannot remember which documentation it was! Does anyone know the command or the documentation where to find it?   The symbol I am looking for:    PS: I have already tried  but it didn't produce anything useful! Also, browsing  wasn't successful.

I've tried latexdef which does not handle --- as the operand. And \texemdash is defined as a character. So that leaves me once again leaning on the collective wisdom of the group :)

I have a mathematical transformation that takes 16 parameters (grouped into 3+8+5) and would like to make a latex command for it, so that I can easily change the notation for it if the need arises.  As far as I know, both \def and \newcommand take a maximum of 9 arguments, is there any (recommended) way to extend this?

I was wondering what the proper LaTeX code would be to display something like this:    You don't have to include the mathematical symbols, what is important is the structure.

I am trying to display a pH scale in LaTeX but Im having trouble figuring it out. All the googling I have been able to do just brings up the pH levels of Latex the material. Can someone offer some advice/resources?

I'm pretty new to Latex, so please bare with me.  I'm trying to add this notation to my document:      I created the above picture from the , but it seems that when I try to apply the same code in my editor (TeXstudio), things are different...    For example, the above picture was produced using the code:    D=\left\{ x\in\mathbb{N}|1\leq x\leq 100 \right\}    But when I write it in my editor (enclosed in the $ sign of course), I get the following error when compiling:      Undefined control sequence. $D=\left{x\in \mathbb   The funny thing is that I was still able to see the output in the preview window (even though the editor shows that this line has error in it). That's the first problem.  The second problem is, although I can see the output in the preview window, it won't be the same as the output I get from the Online Latex Equation Editor. While the Online Latex Equation Editor produces this:      My TeXstudio editor produces this:     Notice the distinction in the N symbol that denotes the set of natural numbers. It is different the what I intended, which is the first version, as it produced by the Online Latex Equation Editor.   What's wrong here? Am I missing a package or something?

The follwing LaTex lines don't print out what I hope to see:  calculate $\rho_i^{t} = \| \mathcal{w}_{i}^{t} - \mathcal{w}_{i}^{t-1} \|_2$   what I get instead of the two w is that:    Can anyone help me please?  Thank you!
