=========================================
The difference between \\dfrac and \\frac
=========================================
In this example, the differences between the \\dfrac and \\frac TeX macros are
illustrated; in particular, the difference between display style and text style
fractions when using Mathtex.
.. versionadded:: 2.1
.. note::
To use \\dfrac with the LaTeX engine (text.usetex : True), you need to
import the amsmath package with the text.latex.preamble rc, which is
an unsupported feature; therefore, it is probably a better idea to just
use the \\displaystyle option before the \\frac macro to get this behavior
with the LaTeX engine.
