[Tex/LaTex] How to type out this integral

math-modesymbols

I am fairly new to TeX, and I am currently using TexStudio.

I am wondering how I can exactly replicate the typesetting of the integral below, including the font and the upright integral sign? What packages, what font?

Thank you.

This seems quite similar to newtxmath with the upint option:

\documentclass{article}

\usepackage{newtxtext}
\usepackage[upint]{newtxmath}

\newcommand{\diff}{\mathop{}\!d}

\begin{document}

\[
\int x^n\diff x
\]

\end{document}

For dubious reasons, lmodern loads the "math extension" font only at a fixed size. You can correct this behavior by declaring it in a different way:

\documentclass{book}
\usepackage{lmodern}
\usepackage{bigints}

\DeclareFontFamily{OMX}{lmex}{}
\DeclareFontShape{OMX}{lmex}{m}{n}{<-> lmex10}{}

\begin{document}
    \begin{align}
    \int_{-Y}^{Y}\left(\frac{X}{\frac{X}{\frac{X}{X}}}\right)dX
    \end{align}

    \begin{align}
    \bigints_{-Y}^{Y}\left(\frac{X}{\frac{X}{\frac{X}{X}}}\right)dX
    \end{align}

\end{document}

I won't show the result which is awful. Please, avoid the "big integrals".

[Tex/LaTex] How to change font for the integral symbol

Define a new math font from a new font family besides the default cmex, for instance, mdbch and euex. Refer to arevmath.sty.

\documentclass{article}
%define a new command for \rm font of int
\DeclareSymbolFont{rmlargesymbols}{OMX}{mdbch}{m}{n}
% or \DeclareSymbolFont{rmlargesymbols}{U}{euex}{m}{n}
\DeclareMathSymbol{\rmintop}{\mathop}{rmlargesymbols}{82}
\newcommand{\rmint}{\rmintop\nolimits}
\begin{document}
$\rmint_a^b$
\[\rmint_a^b \]

\end{document}
