<p>LaTeX is available to users of the vpython module in a Jupyter notebook.</p>
<p>In Web VPython, LaTeX may be used with <a class="reference external" href="https://www.mathjax.org">MathJax</a> to display math equations in the title or caption field of a canvas.  MathJax requires that:</p>
<ul class="simple">
<li><p>All LaTeX backslashes must be replace by double backslashes.</p></li>
<li><p>Expressions must be bracketed by <code class="docutils literal notranslate"><span class="pre">\\(</span></code> and <code class="docutils literal notranslate"><span class="pre">\\)</span></code> intstead of dollar signs.</p></li>
