I am trying to express the roots of a quadratic equation `t^2-3t-7=0' in radical form. I tried \documentclass[12pt]{article} \usepackage{polexpr} \usepackage{xint} \begin{document} \poldef f(t) = t^2-3t-7; \xintdefvar a = (f(2)-2*f(1)+f(0))/2; \xintdefvar c = f(0); \xintdefvar b = reduce(f(1)-a-c); \xintdefvar delta = b^2 - 4*a*c; \xintdefvar t1=reduce((-b+sqrt(delta))/2/a); \xintdefvar t2=reduce((-b-sqrt(delta))/2/a); \[\xinteval{t1}, \quad \xinteval{t2}\] \[t=\frac{1}{2} \left(3-\sqrt{37}\right)\lor t=\frac{1}{2} \left(3+\sqrt{37}\right).\] \end{document} I got How can I get?

How can I make the included image larger than the surrounding \fbox{\includegraphics{img.png}}? I need to include an image with a transparent background that "spills" into adjacent cells of a (tabular) table -- I don't need the fbox finally.

I'm annotating a fraction with TikZ arrows pointing to specific parts. The blue arrow works fine, but the red curved arrow is bisecting the "3" in the denominator instead of arcing over it. Current behavior: The red arrow cuts straight through the middle of "3" Desired behavior: The red arrow should arc upward and over the "3" with clear space. I initially tried adjusting the out angle from 160° to 120° to make it launch upward, but this still results in the arrow bisecting the number. How do I increase the arc height to make the curve clear the "3" completely as shown in the 2nd image? Note: I'm still learning TikZ best practices. If you spot any obvious improvements to the code structure, please mention them.

My .tex file fails to fully compile on my own systems, due to an error with \logo. Here's the relevant error: ./ccmeeting30JAN26.tex:36: Undefined control sequence. l.36 \logo {\includegraphics[width=0.3\textwidth]{aglogo.jpg}} % Institution ... On overleaf, it compiles and adds the logo with no problems. pdflatex is finding all the needed files, so that's not the problem, as far as I can tell. Let me know if you'd like to see the code. Also, I've used the texMemo class for a few years, and this is a new problem for 2026. I'm running texlive 2025, with all updates. Thanks much in advance for any help you may offer.

Are they learning, having fun, enjoying the class, etc.. Our current curriculum - \emph{2 or More} - is good. Liked more by Mary, but okay with Denise and Katie. Linda likes the BGMC curriculum. There are no particular problems, needs, questions or requests. One thing brought up by Denise was the lesson suggestion to get down on the floor and play with the younger kids. Too difficult for her. But we reassured Denise that that was not needed, if it was not possible. All of the teachers believe that they are doing a good job. Salvation and Discipleship are the goals of teaching. ``The teacher hasn't taught until the student has learned.'' May the Lord bless His work in and through you!

In this sample, one would have expected a hyphen at the end of the third line, निरोधम-भिमुखं. Of course, this is a question of conventions, and perhaps the current transformation was made with a convention in mind that hyphenates without actually using hyphens, such as was done in most manuscripts. In modern typesetting however I would expect hyphens to be used. Perhaps it is just a bug?

I am trying to reproduce a manuscript as “photographically” as possible. Sometimes words have been added after a first draft, above a line, centered in between two words. To get this, I used a \makebox with the width of \space and centered content, and within that box, I placed a \raisebox to place the added content vertically. It seemed to do the job just fine until I noticed that the length \space (or " ") which I wanted the box to have gives that box a fixed length (and after all you would indeed expect that in a box), whereas I would like the interword spacing to have the flexibility it has elsewhere, and just obtain a box in the middle of that flexible space. I first thought of a fix that would simply involve putting a half normal space on both sides of a box without width, but I find no such command seems to exist! (\, does not do that). Any ideas?

I'm translating Kazakh problems for the Art of Problem Solving forum, and I faced an obstacle with this problem: It translates like: Aigerim and Batyrkhan play the following game. There is a board of size $2\times2024$ (2 rows and 2024 columns). They take turns, with Aigerim moving first. On her move, Aigerim places a horizontal domino on the board $\boxed{\phantom{a}}\boxed{\phantom{a}}$, covering exactly two squares. On his move, Batyrkhan places a vertical domino on the board $\begin{aligned} \fbox{\rule{0pt}{1.2em}\hspace{1.2em}}[0em] \fbox{\rule{0pt}{1.2em}\hspace{1.2em}} \end{aligned}$, also covering exactly two squares. A player who cannot make a move loses. (Dominoes may be placed only on empty squares.) Who wins if both players play optimally? and I don't know how to do the vertical domino without separation between the squares. AoPS doesn't support features like tikzpicture, so I need to come up with a different method.

I am typesetting a play in LaTeX. I would like all the lines to be numbered but of course the stage directions etc. should be excluded from the line numbers. In MS Word, this is easily by telling word to exclude some lines from the numbering, it then looks like this: Is there a way to acheive this in LaTeX too? My preferred way would be to tell the document to have line numbers everywhere except: in lines where there are stage directions (maybe this can be done by some command?) in lines that consist only of headings (i.e. scene numbering etc.).

But, when I set enlarge y limits={upper, abs=0.125} it creates a strange gap (ymin=0 is no longer respected, and restrict y to domain=0:1 seems to have no effect). • Secondly, what's the best way to configure it so that bars with very small y-values ​​are also visible here? • Unfortunately, I saw this too late: I would also like to eliminate this x-gap between the first bar and the y-axis! \documentclass[margin=5pt]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \begin{document} \begin{tikzpicture}[font=\footnotesize, declare function={ binom(\n,\p,\k)=\n!/(\k!*(\n-\k)!)*\p^\k*(1-\p)^(\n-\k); } ] \begin{axis}[%y=8mm, no effect ymin=0, xmin=0, axis lines=left, axis line style={-latex}, xlabel={$k$}, ylabel={$P(X=k)$}, x label style={at={(axis description cs:1,0)}, anchor=south east, inner xsep=0pt }, y label style={at={(axis description cs:0,1)}, rotate = -90, anchor=north west, inner ysep=0pt, }, yticklabel style={ /pgf/number format/fixed, /pgf/number format/fixed zerofill, /pgf/number format/precision=2 }, ybar=0pt, bar width=1, bar shift=0pt, samples at={0,...,13}, variable=\k, enlarge x limits={upper, abs=0.785}, enlarge y limits={upper, abs=0.125}, %restrict y to domain=0:1,% no effect.... ] \addplot [fill=gray!25] {binom(13, 0.4, k)}; %\addplot [fill=orange, samples at={0,...,4}] {binom(12,0.4,k)}; %\addplot [fill=cyan, samples at={7}] {binom(12,0.4,k)}; \end{axis} \end{tikzpicture} \end{document}

I'm trying to read a simple csv into a datatool database and then populate a table with this data. The persistent error is reported as "Package datatool error: Database 'gradesDB doesn't exist' in the TeXworks console output. I'm using the current TeXworks 2025 full/complete installation. The csv was encoded as uft-8. This csv file is named data.csv (NOTE: In the preview of this post this file appears in a single row format. It is actually written as a 4 row x 3 column form with the first three rows terminated by CRLF) Name,Surname,Grade Albert,Einstein,147 Marie,Curie,159 Thomas,Edison,179 I've consulted online AI and version 3.4.3 2025-12-04 of The Datatool Bundle: Databases and Data Manipulation from Dickimaw Books for documentation.

I know that I can make circular diagrams with the nice smartdiagram package, but arrows do not fit perfectly in a imaginary circle. In fact, the diagram is far from a circle when there are only two or three nodes: \documentclass{standalone} \usepackage{smartdiagram} \begin{document} \smartdiagramset{ connection color=red, module shape= circle, circular distance=2cm, uniform color list=white for 6 items, uniform arrow color=true, arrow color=black} \smartdiagram[circular diagram:clockwise]{foo, bar} \end{document} I know also that there are several examples in this site about making circular diagrams without this package, but translating these examples to diagrams with a different numbers of nodes is complex, so I tried an automated solution with tikz (without really knowing what I was doing, I have to admit) so that I only have to modify a list of nodes in \mylist and little more to obtain the result: \documentclass[border=2mm]{standalone} \usepackage{tikz} \usetikzlibrary{arrows.meta} \begin{document} \begin{tikzpicture}[ > = Stealth, every node/.style = {circle, draw, thick, minimum width=1cm, align=center} ] \def\mylist{foo, bar, baz} % play with this \foreach \x [count=\i from 1] in \mylist {\xdef\n{\i}} \def\radio{2cm} % and this if needed \foreach \texto [count=\i from 0] in \mylist{ \pgfmathsetmacro\ang{-\i*360/\n} \node (n\i) at (\ang:\radio) {\texto}; } \foreach \dummy [count=\i from 0] in \mylist{ \pgfmathsetmacro\j{int(mod(\i+1,\n))} \pgfmathsetmacro\angini{-\i*360/\n} \pgfmathsetmacro\angfin{-\j*360/\n} \pgfmathsetmacro\outang{mod(\angini - 90 + 720, 360)} \pgfmathsetmacro\inang {mod(\angfin + 90 + 720, 360)} \draw[->, thick, line width=1.4pt] (n\i) to[out=\outang, in=\inang, looseness=.9] (n\j); % and with the looseness } \end{tikzpicture} \end{document} Mainly it works. The problem is that like in smartdiagram, the arrows don't perfectly follow an imaginary circle, that was the idea behind getting involved in this business. Playing with looseness is possible to correct a bit the curvature of the arrows, but it's tedious and the result is never perfect. So, the result should be ideally near to the image below (that I modified manually in Inkscape) and still require minimal settings to adapt the code to diagrams of n nodes. Fixes of the MWE as well as alternative approaches are welcome. Edit Thank you all for the excellent suggestions. This time, I am truly sorry I can only accept one.
