Best Practice 4.9.1.1. Keep Inline Mathematics Short.
Longer mathematical expressions in an
<m> element can lead to awkward line breaks, both in HTML output, and especially in PDF generated from LaTeX. And complicated fractions or integrals can introduce abnormal line-spacing that is distracting to a reader. As a rough rule-of-thumb, keep an inline expression shorter than a moderately-long regular word and avoid tall constructions. This should allow LaTeX’s line-breaking algorithms the best chance of success.So a simple, short equality such as \(x=2\) should not cause a problem, but if you want to claim that the probability distribution of the normal distribution has the right scaling factors, \(\int_{-\infty}^{\infty}\frac{1}{\sigma\sqrt{2\pi}}e^{-\frac{1}{2}\frac{\left(x-\mu\right)^2}{\sigma}} dx = 1\text{,}\) there is a good chance it will do less harm to your paragraph of you display it
\begin{equation*}
\int_{-\infty}^{\infty}\frac{1}{\sigma\sqrt{2\pi}}e^{-\frac{1}{2}\frac{\left(x-\mu\right)^2}{\sigma}} dx = 1
\end{equation*}
using the
<me> element described next.
