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?

I am preparing lecture notes in Turkish, and I have a digram for mathematical modelling procedure. But I cannot produce a good output for the following code. When I remove the first three packages, I get my desired output. However, I need to have keep them in my document.

The first image is what I have at the moment, the second image is what I would like to get. As you can see, in the second image the formula font size is a little bit bigger than in the first image. I would like to make all the formulas font size a little bit bigger. I tried using, as suggested , \DeclareMathSizes{14}{15}{7}{7} (note that in beamer I am using 14pt as font size) but it did not produce any effect.  \documentclass[14pt,handout,t]{beamer} \usepackage{lmodern} \usepackage[english,italian]{babel} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \geometry{paperwidth=297mm,paperheight=210mm} \usefonttheme{professionalfonts}  \renewcommand{\sfdefault}{phv} %change font \DeclareMathSizes{14}{15}{7}{7}  \begin{document} \begin{frame} complesso: $\alpha=\alpha_{r}+i\alpha_{i}$ \end{frame}  \end{document}

I wanted to type an equation in LaTeX. But it is too long to fit into one line. It involves big arrays with many columns so I cannot split it. I wanted to reduce the font size so that it can fit in one line. However, \small doesn't work in the equation environment.

I am writing two equations in an align environment:  \begin{align} x^2+y^2=z^2, \\ x^2=7, \end{align}   I would like the first equation to be labelled with e.g. (1.1) and the second equation to be labelled (1.1'), rather than (1.2).  Is this possible to automate? Do I need to use a hack to manually place the equation number after my second equation? e.g.  \newcommand{\hack}{\hfill({\eqnum}')} % Sketch - I don't know what command to use. \begin{align} x^2+y^2=z^2, \\\nonumber x^2=7,\hack \end{align}   If so, what command can I use to get the equation number? i.e. what should my command \hack be?

The reigning answer for the  completely disregards math-mode.  This might be preferred when all math equations are set display style, but a matching font is a must for in-line equations.  My current MWE (based on the one given ) only gives the text-mode items in sans, but any math remains in serif style (in-line, numerical-only equations look particularly hideous).  How can I set math in sans-serif as well?    \documentclass[]{article}  \usepackage{helvet} \renewcommand{\familydefault}{\sfdefault}  \usepackage[math]{blindtext}  \begin{document}  Text looks particularly bad when you have $123,400$ number-only equations in-line.  \blindmathpaper  \end{document}

The commath package use the TeX command \ifinner to select between inline math mode and display math mode. Because of this, it fail to work properly with some display math environments.  In the breqn package, we find:     The test \ifinner is unreliable for distinguishing whether we are in a displayed formula or an inline formula: (...) So we provide a more reliable test. But it might have been provided already by the amsmath package.   The more reliable test should be \if@display but only replace \ifinner with  \if@display in commath.sty not work. Any suggestion?

With a regular article/report/... class, you can use the showframe package to draw outlines of where the various regions of the page lie.  I cannot get the same functionality with beamer, however.  Using geometry with its showframe option similarly does not work.  How can I get this functionality with beamer?  MWE:  \documentclass{beamer}  %\usepackage[showframe]{geometry}  % Doesn't work \usepackage{showframe}             % Doesn't work  \begin{document}  \begin{frame}{Slide Title} \centering Centered Text \end{frame}  \end{document}   Edit:  A similar question is posed  that asks for a diagram depicting the layout of the page with lengths of various parameters given.  The \layout package gives this output when applied to the MWE:    While this output gives margin information and general layout information, it does not give the visual output that I am looking for, with boxes overlaid on my own content. I am less interested in seeing the value of margins and other lengths than I am in visualizing the fit of my own content on the slide and seeing how close the boxes actually are to content.  This is why I desire functionality more close to what the showframe package would provide.

My intention is to create equation which looks similar to one of examples below (I prefer the second one).     There should be an arrow from JKL to DEF and GHI and from GHI to DEF.   Neither alignment nor equation environment have to be used. Anything that will do is appreciated. Cheers.

I would like to use a small image in an equation, where a symbol like \alpha might otherwise be. Is there a nice way to do this?

Based on this question:  I got some nice tools for illustrating to my students how to find the product of a number or a variable and a parenthesis.   However, the solution fails when I should have two sources in one line, for instance when expanding (a+3)(b+4). I would also be able to place a small number next to or above the arrowhead to indicate the first calculation, the second, etc. The second set of arrows could just as well go below the expression, not above it, to simplify things.   I could of course define myself a new set of macros similar to the existing ones, for instance \sourceTwo and \targetTwo, but it feels like this could be done more elegant.   MWE:  \documentclass[]{article} \usepackage[utf8]{inputenc} \usepackage{tikz}  \newcommand\source[1]{%     \tikz[remember picture,baseline,inner sep=0pt] {%         \node [name=source,anchor=base]{$#1$};     }%     \setcounter{target}{0} } \newcounter{target} \newcommand\target[1]{%     \tikz[remember picture,baseline,inner sep=0pt] {%         \node [name=target-\thetarget,anchor=base]{$#1$};     }%     \stepcounter{target}% } \newcommand\drawarrows{     \tikz[remember picture, overlay, bend left=45, -latex] {         \foreach \i [evaluate=\i as \n using int(\i-1)] in {1,...,\thetarget} {             \draw (source.north) to (target-\n.north);         }     } }  \begin{document}  \begin{equation}     (\source{a}+4)(\target{b}+\target{3}) = \drawarrows \end{equation}  \end{document}

I need an appearing effect for text like the one (in javascript) here .  However I don't know how to insert js code into LaTeX (apart from using the AcroTeX Bundle) and that would also force me to use Acrobat Reader, so I'd like to implement a similar effect in Beamer. Is it possible?  (of course I would love to see alternative approaches to this)
