I'm using standard template and I'm getting the following partial derivative operator in the left of picture below.

   \documentclass{article}
   \usepackage{amsfonts,amsmath,amssymb,amsthm}
   \begin{document}
   \begin{equation*}
   \partial
   \end{equation*}
   \end{document}

I would like to know how to obtain the partial derivative operator in the right. Are there other font styles for this symbol?

Compiling with XeLaTeX engine the desidered symbol have a name: Unicode Character “∂” (U+2202). Remembering that this symbol lie on font Times New Roman you will obtain the partial derivative operator in the right.

enter image description here

\documentclass[a4paper,12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{fontspec}
\setmainfont{Times New Roman}

\begin{document}
$\displaystyle\frac{∂^2f}{∂^2x^2}+ \frac{∂^2f}{∂^2y^2} +\frac{∂^2f}{∂^2z^2}=0$
\end{document}

Edit

\documentclass[a4paper,12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{fontspec}
\setmainfont{Times New Roman}
\usepackage{scalerel}
\begin{document}
\[\scaleobj{5}{\partial \to} \scaleobj{5}{∂}\] 
\end{document}

PS: \partial = ∂.

  • However, since the symbol of partial derivative is not a variable, it is officially (according to standards) correct to write it upright (not curly). Is it possible to do this, maybe just changing the font of it? – umby Jan 08 '24 at 12:05
