+## MathJax 
+
+Support for MathJax Version 3.0 is included in the template:
+
+$$
+\displaylines{
+\nabla \cdot E= \frac{\rho}{\epsilon_0} \\\
+\nabla \cdot B=0 \\\
+\nabla \times E= -\partial_tB \\\
+\nabla \times B  = \mu_0 \left(J + \varepsilon_0 \partial_t E \right)
+}
+$$
+
+The default delimiters of `$$...$$` and `\\[...\\]` are supported for displayed mathematics, while `\\(...\\)` should be used for in-line mathematics (ex., \\(a^2 + b^2 = c^2\\))
+
+**Note** that since Academic Pages uses Markdown which cases some interference with MathJax and LaTeX for escaping characters and new lines, although [some workarounds exist](https://math.codidact.com/posts/278763/278772#answer-278772).
