## HEXO Plugins 🔗

I’m slowly starting to understand how this software works. I have also been looking around at the available plugins for it and found this interesting one called *hexo-filter-mathjax*. It provides rendering of math equations. Unlike the Katex.js library, this is all rendered on my local machine before I push it to GitHub. That means I don’t need to worry about a failed JS library on a visitor’s device. And, it means my site loads faster as it’s one less JS library to download. Below I wrote a few tests.

My interest in having this feature is to support some of the scientific articles I would post on rare occasions.

More information on how to write these beautiful equations can be found here:

E(kWh) = P(W) × t(hr) / 1000

```
E_{(kWh)}
=(\frac{P_{W}t_{hr}}{1000})
```

```
\begin{eqnarray\*}
\nabla\cdot\vec{E}&=&\frac{\rho}{\epsilon_0}\\\\
\nabla\cdot\vec{B}&=&0\\\\
\nabla\times\vec{E}&=&-\frac{\partial B}{\partial t}\\\\
\nabla\times\vec{B}&=&\mu_0\left(\vec{J}+\epsilon_0
\frac{\partial E}{\partial t}\right)\\\\
\end{eqnarray\*}
```

```
i\hbar\frac{\partial}{\partial t}\psi=-\frac{\hbar^2}{2m}\nabla^2\psi+V\psi
