[Tex/LaTex] Set the default math font back to the original

fontsmath-modetimes

Long time lurker, first time poster, but my time has come.

I highly suspect the answer to my question is easy, but I can't find how to solve my problem. I'm typesetting my Ph.D. thesis and I'm using a template built by some students of my University. The default fonts of this template were changed to resemble a document made in Microsoft Word, for reasons I really don't comprehend (the default LaTeX font is so beautiful!).

I managed to revert the text back from Times New Roman to the default Computer modern Roman with a command

\renewcommand*\rmdefault{cmr}

But I couldn't find how to revert the math font to the default. Currently, for example, my equations are like this:

While I want them to be like this:

In my document I renamed the \vec{} command to produce boldface text instead of putting the small arrow. The second figure was produced with an online LaTeX formula editor because I just wanted a figure with the default math font.

The differences on both fonts are noted mainly in the greek letter tau and the roman letter u.

A MWE is as follows, without the several included packages. None of them are related to fonts, except amsmath is almost a default. The font is defined somewhere on the class ufscThesis.cls, which I'm not comfortable editing. I suspect it is possible to, on the document, globally redefine the math font in the same way I redefined the text font to CMR without touching on the class file.

\begin{document}
   \begin{equation}
       \rho\Delta\vec{u}=\vec{F}\tau
   \end{equation}
\end{document}

How do I do it?

I solved it!

The class I'm using just configures a document according to ABNT rules (a Brazilian normatization organ), based on a LaTeX package called ABNTex (aptly named for ABsurd Norms for Tex). Since I found no mentions whatsoever about fonts on the class ufscThesis.cls, neither the modifications I did to force the default font worked, I decided to take a look on the class abnt.cls. There I found these lines:

%%%%%%    Opcao de fonte Times como romano default

\ifthenelse{\boolean{ABNTtimesfont}}% if `times'option enabled...
 {\IfFileExists{mathptmx.sty}%  try `mathptmx' first
   {\RequirePackage{mathptmx}}% 
    {\IfFileExists{mathptm.sty}% if not installed, try `mathptm'
       {\RequirePackage{mathptm}}%
       {\IfFileExists{times.sty} % 
         {\RequirePackage{times}}%
         {\renewcommand{\rmdefault}{cmr}}%
       }%
    }%
  \IfFileExists{helvet.sty}% including also Helvetica as sans serif.
    {\RequirePackage{helvet}}%
    {\IfFileExists{helvetic.sty}%
       {\RequirePackage{helvetic}}%
       {\renewcommand{\rmdefault}{phv}}%
    }%
  }%

It was just a matter of commenting this small snippet an, voilà, sexy beautiful equations again!

Thanks for the help!!

[Tex/LaTex] French math style with default font

You wrote,

not mentioning the fact that unicode-math seems to clash with amssymb

What's the basis for this claim? The packages get along fine as long as amssymb is loaded first.

If you can use either XeLaTeX or LuaLaTeX to compile your document, specifying the option math-style=french while running \setmathfont lets you achieve all of your locale-related formatting objectives.

% !TEX TS-program = lualatex
\documentclass{article}
\usepackage{amsmath,amssymb,booktabs}
\usepackage{unicode-math}
\setmainfont{Latin Modern Roman}
\newcommand\blurb{%
  abcd \quad ABCD \quad \gamma\delta\phi\psi\omega 
  \quad \Gamma\Delta\Phi\Psi\Omega}

\begin{document}
Four math styles:

$\begin{array}{@{} ll @{}}
\toprule
$TeX$     & \setmathfont{Latin Modern Math}[math-style=TeX]\blurb \\
$ISO$     & \setmathfont{Latin Modern Math}[math-style=ISO]\blurb \\
$french$  & \setmathfont{Latin Modern Math}[math-style=french]\blurb \\
$upright$ & \setmathfont{Latin Modern Math}[math-style=upright]\blurb \\
\bottomrule
\end{array}$
\end{document}

How to make a document in Times New Roman font of English, Greek, number, all for the text, the math and the text in math mode

This worked for me.

\documentclass{article}
%\usepackage{amsfonts}
%\usepackage{amsthm}
%\usepackage{amsmath, amssymb}
%\usepackage{tgtermes}
%\usepackage{pslatex}
\usepackage{unicode-math}
\usepackage{polyglossia}
    \setdefaultlanguage{english}
    \setotherlanguages{greek,russian}
 
\setmainfont{Times New Roman}
\setmathfont{TeX Gyre Termes Math}[Scale = MatchLowercase]
\newfontfamily\greekfont{Times New Roman}[Script=Greek, Language=Greek]
\newfontfamily\russianfont{Times New Roman}[Script=Cyrillic, Language=Russian]


\begin{document}
\textgreek{χ}\textsuperscript{2} distribution
\begin{align*}
&\chi^2\text{\ distribution}\\
&f(x)=\frac{1}{\beta^{\alpha} \Gamma(\alpha)} x^{\alpha-1} e^{-\frac{x}{\beta}} \qquad \alpha>0, \beta>0\\
&\text{for\ } \ \alpha=\frac{\nu}{2}, \beta=2 \qquad f(x)=\frac{1}{2^{\frac{\nu}{2}} \Gamma\left(\frac{\nu}{2}\right)} x^{\frac{\nu}{2}-1} e^{-\frac{x}{2}} \qquad x>0
\end{align*}
\end{document}

The unicode-math package lets you cut the gordian knot of legacy 8-bit font packages.

If you don't like TeX Gyre Termes Math’s letters, you could add these lines to replace them with Times New Roman:

\setmathfont{Times New Roman Italic}[range=it]
\setmathfont{Times New Roman}[range=up]
\setmathfont{Times New Roman Bold Italic}[range=bfit]
\setmathfont{Times New Roman Bold}[range=bfup]

In pdftex, you might load \usepackage{tempora,newtxmath} and \usepackage[greek, russian, english]{babel}.
