When using fractions in \polylongdiv, the vertical spacing turns out rather awkward. If no fractions are used for the coefficients, the spacing is fine. I have tried to adjust the vertical spacing using arrayrowsep=..., but without any visible change. Is it possible to adjust this vertical spacing for fractions? \documentclass{article} \usepackage{polynom} \polyset{style=C,div=:,arrayrowsep=1cm} \begin{document} \polylongdiv[arrayrowsep=1cm]{(1/5)x^2-(3/7)x+4/9}{x-1/2} \polylongdiv[arrayrowsep=1cm]{5x^2-5x+6}{x-3} \end{document}

I would like to use Initials in a nice poetry book and need for German Umlaute (Ä Ö Ü) those designs. And the general question is: Why are Initials always without special characters, also for other languages other than German? And for now: How is it possible to produce Ä Ü Ö manually? \documentclass[a4paper]{article} \input Zallman.fd \pagestyle{empty} \begin{document} \begin{center} \fontsize{60pt}{72pt}\usefont{U}{Zallman}{xl}{n} ABCDE \\ FGHIJK \\ LMNOP \\ QRSTU \\ VWXYZ \\ ÄÖÜ \\%<-- Special characters Umlaute Initials?! \end{center} \vfill \begin{center} Font name: ``Zallman'' (ZallmanCaps) \end{center} \end{document} Is there a trick to get them nice?

I need all binomial coefficients for n=1..100 and k=1..100 several times, so I wrote a code with xint: \xintdefvar BinomialArray = ndseq(binomial(n,k), n=1..100; k=1..100); \xintdeffunc abinomial(n,k):=BinomialArray[n-1,k-1]; I measured out for that: ******************************************** *** TOTAL COMPILATION TIME REPORT: *** (l3benchmark) + TOC: 2.27 s ******************************************** This is OK, but I asked myself: Is there any way I can store the array (in a file?) so that it doesn't have to be recalculated on every new run? \documentclass[paper=a5, paper=landscape]{scrarticle} \usepackage[margin=10mm]{geometry} \usepackage{xintexpr} \usepackage{amsmath} \begin{document} \xintdefvar BinomialArray = ndseq(binomial(n,k), n=1..100; k=1..100); \xintdeffunc abinomial(n,k):=BinomialArray[n-1,k-1]; %Test: \xinteval{BinomialArray[100-1,50-1]} works Test: $\dbinom{100}{50}=\xinteval{abinomial(100, 50)}$ % Show complete array - on your own risk :() %\newpage %\begingroup %\tiny %BinomialArray = \xintthealign\xintexpr BinomialArray\relax %\endgroup \end{document}

As what my knowledge could tell, It's possible to create a triangle with only 2 coordinates to make real angles to be exact, and using path to create long rays and naming the intersection of those rays and finally connect them with \draw. MWE: \documentclass[tikz, border=10pt]{standalone} \usepackage{siunitx} \usetikzlibrary{intersections} \begin{document} \begin{tikzpicture}[scale=2] \clip (0,0) rectangle (5,2.1); \coordinate (A) at (0,0); \coordinate (C) at (5,0); \path[name path=AB] (A) -- ++(37:4); \path[name path=BC] (C) -- ++(137:4); \path[name intersections={of=AB and BC, by=B}]; \draw[thick] (A) -- (B) -- (C) -- cycle; \end{tikzpicture} \end{document} There is a noticable difference if I comment \clip in the 6th line. Without it, it's going to be a white space... It's impractical to calculate the height of the object if I make another drawing with more complicated shape. So, is it possible to autocrop the exceeding lines? What I meant by exceeding lines is like the cyan lines in the figure below. It's because they contribute to white space if I change \draw to \path: So, if possible, I want TikZ to automate cropping the intersection, in other words, getting rid of those exceeding lines without estimating like how much the height is (would consume loads of time if I make other complicated figures with intersections). To illustrate what I actually want, roughly I want something like this: Yes, I deliberately cropped it poorly to give an example as to what it shows if I gave them an incorrect clipping, which I wish I didn't need to clip it, but instead, I wish TikZ only read the intersection point and two given coordinates to draw.

I have some code here that calculates the functions \bdceval{\n}{\p}{\k}, row by row, for fixed \n and \k values ​​and values ​​p from a list \def\pList{0.1, 1/6, 0.25, 0.3, 0.4, 0.5}. It works and is correct. But I'm wondering: Is this well-designed in terms of performance? I can only manage to implement \makePListRow{\n}{\k} with two commands. \documentclass{article} \usepackage{tikz} \usepackage{xintexpr} \def\pList{0.1, 1/6, 0.25, 0.3, 0.4, 0.5} % Function: \xintNewFloatExpr{\bdceval}[3]{add(binomial(#1,v)*#2^v*(1-#2)^(#1-v), v=0..#3)} % Commands for List: \newcommand{\myRowMapper}[1]{\xintRound{4}{\bdceval{\n}{#1}{\k}}} \NewExpandableDocumentCommand{\makePListRow}{mm}{% \xintListWithSep{, }{% \xintApply{\myRowMapper}{\xintCSVtoList{\pList}}% }% } \begin{document} \foreach \n in {2,3,7}{% \foreach \k in {0,...,\n}{% \n, \k, \makePListRow{\n}{\k} \par }% } \end{document}

Here, for this example I'm always including the same page #1 and using a sample image to be able to compile it. When I look at my tags I see this: <Document> <Private> <Figure> <p> <Figure> <p> As I declared the artifact, the <Private> tag shows the appropriate alt-text. However, the <Figure> tags contain the path to the image as alt text. How can I change that? I do not want that path to be made public. And what are the <p> tags? Where did they come from?

For this example purpose, I'm adding the example-image.pdf as a page so the code can be compiled without external files. The <Artifact> I declare shows as a <Private> tag inside the <Sect> tag. But in this particular file I'm working, it would make more sense for it to be at the same level as the <Sect> tag instead of inside it. Is this possible? In other words, I want this: <Document> <p> <p> <Sect> <H1> <p> <Private> instead of this: <Document> <p> <p> <Sect> <H1> <p> <Private> Note: The code is compiled with LuaLaTeX using MiKTeX 26.2.

I wish to draw something like this: I can draw the two lines, though it is difficult to be precise. However I don't know what to do next as for the dashed line and the arrow line. The dashed lines are perpendicular to MK and JL, but the arrow line are parallel to those lines. And the difficult part is connecting the dashed line with the arrow line. I failed to draw the 90 degree sign, it looks too big and ugly.

I'm a PhD student evaluating cloud LaTeX editors for writing my dissertation. I've used Overleaf for years but I'm noticing a new wave of editors claiming AI-powered features. I've looked at: Overleaf — familiar, but not reliable, and compilation is slow on large documents OpenAI Prism — new, AI-native, backed by OpenAI (I don't trust OpenAI) Papeeria — free tier, minimal AI Bibby AI (trybibby.com) — seems focused on bibliography error detection specifically with a good AI benchmark they published outperforming OpenAI and Overleaf. My question is: for someone writing a 200-page dissertation with 300+ citations, what are the meaningful technical differences between these editors, particularly: How does real-time bibliography validation differ across platforms? Do any of them integrate with arXiv directly? Is AI autocomplete in LaTeX actually useful or is it mostly marketing?

Doing this in the usual way with enumitem currently fails. A brief example follows.

I am using babel package with Spanish style (in amsart class), which puts acute accents in math symbols such as \lim, \max, \inf, etc. It is actually nice, because it keeps all the formatting in the same language and style. However, it doesn't put the accent in \varprojlim, which doesn't go with the general layout. Is it possible to make \varprojlim have the accent as everything else? MWE: \documentclass{amsart} \usepackage[spanish]{babel} \usepackage{amssymb,amsfonts,amsmath} \begin{document} \[ \lim \; \inf \; \max \] \[ \varprojlim \] \end{document} Result:

It seems (or is apparently) that thickness of lines is hard coded. Consequently when drawing a line, the use for example of scale=2 only makes the line longer and its thickness is not changed, see MWE below: \documentclass[margin=3mm, varwidth]{standalone} \usepackage{tikz} \usetikzlibrary{arrows.meta} \tikzset{LA/.style = {-Straight Barb, line width=1mm}} \begin{document} \begin{tikzpicture} \draw[LA] (0,0) -- ++ (2,0); \end{tikzpicture} \begin{tikzpicture}[scale=2] \draw[LA] (0,0) -- ++ (2,0); \end{tikzpicture} \end{document} Is there some trick by which the thickness of the line will also be scaled? The best way would be as option of the line style, which will have effect just on this particular line. My quick search on this site so far didn't give me any suggestion ...

The following loop is an example of a loop that, starting from a certain sequence member, is rounded to 1.0000. How can I break the loop at the second term, which is 1.0000 (in this example, that's the 13th)? Note: I'm using TikZ and xint; both are possible options. \documentclass[margin=5pt, varwidth]{standalone} \usepackage{tikz} \usepackage{xintexpr} \begin{document} \foreach \x in {1,...,15}{%% \x: \xintround{4}{\xinteval{1-exp(-\x/1.2)}}\par }%% \end{document}

I'm creating a landscape booklet with top ring binding, and I want it to be read across both pages when opened. I've been trying to set up inner and outer margins, but the information I find mostly covers how to do this when the book is bound on the left edge. What I need is to have different top and bottom margins for odd and even pages, like: Odd pages: 25mm top margin, 10mm bottom margin Even pages: 10mm top margin, 25mm bottom margin I’ve tried using the memoir and book classes, along with geometry, but I’m open to other suggestions as well. Could someone explain the recommended setup for this kind of book format? Any help would be greatly appreciated! A (blurry, will update..) picture of the layout I am thinking of. Thanks!

I am giving a try at coffins, and I joined two coffins to typeset material side by side on a line. However, \TypesetCoffin does not put the resulting coffin at the left hand side of the page, but introduces a small gap, as evidenced by the boxes below. Why is that, and how do I tell it not to ? \documentclass{article} \usepackage{showframe,xcoffins} \fboxsep 0pt \begin{document} \noindent \NewCoffin\CoffinExG \NewCoffin\CoffinExD \SetVerticalCoffin\CoffinExG{.72\textwidth}{material} \SetVerticalCoffin\CoffinExD{.28\textwidth}{\hfill material} \JoinCoffins\CoffinExG[b,r]\CoffinExD[b,l] \fbox{\TypesetCoffin\CoffinExG} \end{document}

I draw an arrow with a label like this. \documentclass[dvipdfmx]{article} \usepackage{tikz} \usetikzlibrary{arrows.meta} \begin{document} \begin{tikzpicture}[auto=left] \node[name=A] at (0,0) {$A$}; \node[name=B] at (1,0) {$B$}; \draw[->] (A) -- (B) node[pos=0.5]{$f$}; \end{tikzpicture} \end{document} I like this notation because the order is “a coordinate, a coordinate, and a label.” This is more readable than “a coordinate, a label, and a coordinate.” I want to bend the arrow while keeping this order. I tried the following: \documentclass[dvipdfmx]{article} \usepackage{tikz} \usetikzlibrary{arrows.meta} \begin{document} \begin{tikzpicture}[auto=left] \node[name=A] at (0,0) {$A$}; \node[name=B] at (1,0) {$B$}; \draw[->] (A) to[bend left=30] (B) node[pos=0.5]{$f$}; \end{tikzpicture} \end{document} However, this does not work properly—the label appears at coordinate A. I know I can achieve this with a \newcommand, but is there another way? Thank you.

Why can't I use \newline? Even entering and giving it \vspace doesn't work. \documentclass[border=6pt]{standalone} \usepackage[table]{xcolor} \usepackage{array} \definecolor{headorange}{RGB}{255,127,0} \definecolor{creamlight}{RGB}{255, 242, 215} \definecolor{creamdark}{RGB}{255, 255, 143} \arrayrulecolor{white} \setlength{\arrayrulewidth}{1.6pt} \renewcommand{\arraystretch}{1.9} \setlength{\tabcolsep}{0pt} \newcolumntype{C}[1]{>{\centering\arraybackslash}m{#1}} \newcolumntype{H}{>{\columncolor{headorange}\color{white}\centering\arraybackslash\bfseries\itshape}m{1.25cm}} \newcolumntype{L}{>{\columncolor{creamlight}\centering\arraybackslash}m{1.8cm}} \newcolumntype{D}{>{\columncolor{creamdark}\centering\arraybackslash}m{1.8cm}} \begin{document} \begin{tabular}{|H|L|D|L|D|L|D|} \hline $x$ & $-1$ & $-0.8$ & $-0.4$ & $0$ & $0.4$ & $1$ \\ \hline $y$ & & $1.4$ & & $-1$ & $-0.6$ & \\ \hline \end{tabular} \newline \vspace{4mm} \begin{tabular}{|H|L|D|L|D|L|} \hline $x$ & $1.2$ & $1.6$ & $2$ & $2.4$ & $2.8$ \\ \hline $y$ & & $2.6$ & & & \\ \hline \end{tabular} \end{document} I want the second table on the right side is exactly under the first table and they are left aligned. Like this:

I'm using https://tex.stackexchange.com/a/647838/141947 to operate over a list of image files to include them easily in a document.

I have an MWE that when processed (lualatex) produces an error ! Argument of \__math_grab_dollar_delim:w has an extra }. which, as far as I know, is not true and impedes the processing of the file. When you comment the DocumentMetadata statement line, the file process fine and produces a PDF fine. \DocumentMetadata{pdfversion=1.7, pdfstandard=A-2b, lang=en-US} \documentclass{report} \usepackage{tikz-cd} % Enable modern LaTeX3 programming syntax \ExplSyntaxOn \NewDocumentCommand{\testinput}{ m } { \file_input:n { #1 } } \ExplSyntaxOff \begin{filecontents*}{diag.tex} \begin{tikzcd}[sep = .8 cm] S^2 \arrow[d, "\pi"] \arrow[r, "\pi"] & (P^2,d) \\ P^2 \arrow[ru, "{\overline{\pi}}"] \end{tikzcd} Since $P^2$ is compact... \end{filecontents*} \begin{document} \testinput{diag.tex} \end{document} I read the DocumentMetadata documentation and it mostly says that the command is a statement, and does not elaborate on the implications that it may have on the processing of the file. The numbers I choose for the example only implies that when you save a file as PDF/A-2b, you are creating a PDF 1.7 file that has been stripped of prohibited features (like JavaScript, encryption, and external references). How does one determine what allows the file to be processed and what not?

I would like to cite theorems in my manuscript by specifying the reference in the theorem title. I tried using the following code: \begin{theorem}[{\cite[Thm.~2.5]{reference_paper}}] Statement of the theorem \end{theorem} or \begin{theorem} \cite[Thm.~2.5]{reference_paper}. Statement of the theorem \end{theorem} These produce the first two results shown in the attached image, but I would prefer something similar to the third row. Being able to remove the space after '(' in the first example would also be fine. Do you have any suggestions? Thanks in advance! This question is similar to this, but I do not want to specify the number manually and was looking for a more LaTeX-style way of doing it.

I'm working on a LaTeX document where I have multiple image files, some of which have a -converted version. For example, my files might look like this: a.png b.png b-converted.png c.png c-converted.png d.png I want to include the images in my document using a command like: \includegraphics{a.png} % includes a.png \includegraphics{b.png} % include b-converted.png \includegraphics{c.png} % include c-converted.png \includegraphics{d.png} % includes d.png That is, the logic should be: If basename-converted.ext exists, include that. Otherwise, include the original file: basename.ext. MWE \documentclass{article} \usepackage{graphicx} \begin{document} \includegraphics{a.png} \includegraphics{b-converted.png} \end{document} EDIT: I should work with multiple multiple file extension, like png, jpg, pdf, svg ...
