+\subsection{Using SymPy}
+
+Programming languages and spreadsheets use a standard syntax to enter
+math formulae. Using a great Python library called
+\href{https://www.sympy.org}{SymPy}, you can get \LaTeX{} formulae
+from math expressions. You don't have to be proficient in Python;
+just use the standard math syntax.
+
+This is a sample SymPy session. We want to obtain the \LaTeX{}
+code for the expression $\left(\frac{x}{2} - \frac{2
+y}{3}\right)^{3}$ and for its expansion $\frac{x^{3}}{8} - \frac{x^{2}
+y}{2} + \frac{2 x}{3}y^{2} - \frac{8 y^{3}}{27}$:
+
+\begin{Verbatim}
+In [1]: from sympy import *
+
+In [2]: init_session()
+IPython console for SymPy 1.9 (Python 3.10.6-64-bit) (ground
+types: python)
+
+These commands were executed:
+>>> from __future__ import division
+>>> from sympy import *
+>>> x, y, z, t = symbols('x y z t')
+>>> k, m, n = symbols('k m n', integer=True)
+>>> f, g, h = symbols('f g h', cls=Function)
+>>> init_printing()
+
+Documentation can be found at https://www.sympy.org
+
+In [3]: expr = (x/2 - 2*y/3)**3
+
+In [4]: latex(expr)
+Out[4]: '\\left(\\frac{x}{2} - \\frac{2 y}{3}\\right)^{3}'
+
+In [5]: latex(expr.expand())
+Out[5]: '\\frac{x^{3}}{8} - \\frac{x^{2} y}{2} + \\frac{2 x}{3}
+y^{2} - \\frac{8 y^{3}}{27}'
+\end{Verbatim}
+
+Now you can copy and paste the resulting formulae into your editor,
+only changing \ltx{\Bs{}\Bs} to \ltx{\Bs}.
+
+If you are reasonably proficient in Python, you may be interested in
+the \href{https://www.ctan.org/pkg/python}{python} \LaTeX{} package and the

-When you typeset your document with \cmd{latex} then \app{dvips},
-graphic inclusion only works with \texttt{EPS} files; \app{pdflatex}
-accepts JPG, PNG, and of course PDF files. The latter choice might be
-preferable for most users.
-
-There are several packages that convert common graphic formats like
-\file{.jpg}, \file{.gif}, \file{.png} etc. to \file{.eps} and/or
-\file{.pdf}; for example, ImageMagik (\url{http://www.imagemagik.org})
-and The GIMP (\url{http://www.gimp.org}). However, these applications
-produce huge \PS{} files.
-
-Best results are obtained using applications that wrap the bitmap,
-turning it into a compact \PS{} file. You'll want to use \app{jpeg2ps}
-(\url{http://www.pdflib.com/jpeg2ps/index.html}) or \app{bmeps}
-(\href{http://www.ctan.org/tex-archive/support/bmeps}
-{CTAN://support/bmeps}). The former is often the best choice for
-wrapping \file{.jpg} files, but the latter handles more graphics
-formats.
-
-If you wish to make both \file{.pdf} and \file{.ps} from the same
-source file, include these commands:
