LaTeX is available to users of the vpython module in a Jupyter notebook.

In Web VPython, LaTeX may be used with `MathJax <https://www.mathjax.org>`_ to display math equations in the title or caption field of a canvas.  MathJax requires that:

* All LaTeX backslashes must be replace by double backslashes.
* Expressions must be bracketed by ``\\(`` and ``\\)`` intstead of dollar signs.

.. code-block::

	box()
	scene.caption = "Final kinetic energy = \\( \\dfrac {1} {2}mv_i^{2}+\\int _{i}^{f}\\vec{F}\\cdot d \\vec{r} \\)"
	scene.title = "\\(\\dfrac {5} {7} \\)"
	MathJax.Hub.Queue(["Typeset",MathJax.Hub])

To typeset only a specific element:

.. code-block::

	scene.title = "\\(\\dfrac {3y} {4x} \\)"
	MathJax.Hub.Queue(["Typeset",MathJax.Hub,scene.title])
