• Use MathJax CDN Service? [_]

  • Oh god no, why would I want to report every visitor’s actions?
• Custom MathJax location? http://example.com/MathJax/MathJax.js

Usage ∞

Native MathJax syntax, e.g.:

• $$E=mc^2$$

• \(E=mc^2\).

However, if this is the only syntax used, the plugin must be explicitly told to load MathJax for the current page.

This can be achieved by adding a [mathjax] shortcode anywhere in the post.

For posts with both [latex]x[/latex] and $$x$$ syntaxes this is unnecessary.

e.g. this:

[latex]
\alpha = \left( \frac{e}{q_\mathrm{P}} \right)^2 = \frac{e^2 c\mu_0}{2h} = \frac{1}{4 \pi \varepsilon_0} \frac{e^2}{\hbar c} = \frac{k_\text{e} e^2}{\hbar c} = \frac{e^2}{2\varepsilon_0 c h} = \frac{c \mu_0}{2 R_\text{K}} = \frac{e^2 Z_0}{2h} = \frac{e^2 Z_0}{4\pi \hbar} = \frac{Z_0}{2R_K}
[/latex]

becomes:

\(\alpha = \left( \frac{e}{q_\mathrm{P}} \right)^2 = \frac{e^2 c\mu_0}{2h} = \frac{1}{4 \pi \varepsilon_0} \frac{e^2}{\hbar c} = \frac{k_\text{e} e^2}{\hbar c} = \frac{e^2}{2\varepsilon_0 c h} = \frac{c \mu_0}{2 R_\text{K}} = \frac{e^2 Z_0}{2h} = \frac{e^2 Z_0}{4\pi \hbar} = \frac{Z_0}{2R_K}\)
