Description
The KaTeX WordPress plugin integrates the superfast KaTeX math typesetting engine with your WordPress website. The plugin allows you to put LaTeX in a [latex]...[/latex]
shortcode, and beautiful math appears on your post or page.
The plugin also has an option to use the excellent jsDelivr CDN to load the KaTeX scripts, further increasing the performance of the plugin.
Equations in [latex display="true"]...[/latex]
will be rendered in display mode (rather than inline mode) and centered on its own line.

Installation
 Upload the
katex
folder to the/wpcontent/plugins/
directory  Activate the plugin through the ‘Plugins’ menu in WordPress
 Use the
[latex]
shortcode in your posts and pages
FAQ
 Wait – I use MathJax and it’s fine!

KaTeX is fast. It’s really fast, compared to MathJax. In fact, it’s a staggering 35 times faster than MathJax. Your page will load much faster with KaTeX, especially if it’s heavy with equations.
 How about Jetpack?

Jetpack has a LaTeX plugin that uses the WordPress.com service to render the equations. However, it uses images, which look ugly when zoomed in, or on highDPI (“retina”) displays. Also, it depends on WordPress.com’s servers, and a lot of equations can make the page slow (too many requests).
Reviews
Perfect Application
Its works fine with wordpress
Works out of the box
Thanks!
Amazing and beautiful!
This is an amazing plugin. I tried many other LaTeX plugins, even the one provided by jetpack. None of them produce the elegant beautiful math symbols like this plugin. It works beautifully, it’s very easy to use, and over all, I highly recommend it over other LaTeX plugins. Well done to the author of this plugin, truly an amazing job.
Excellent
Worked right out of the box in WP 4.3.1. Nice solution using the powerful KaTeX math rendering library.
Furthermore, I could tweak the appearance using CSS. (I felt that a particular symbol needed a little more space around, so made the change by adding one CSS adjustment in my child theme.)
Functional and selfsufficient
Elegantly functional and selfsufficient. I am not a fan of the increasing trend towards plugins that require support of offsite server resources, like Jetpack’s sending of latex to WP’s servers for processing. Anything I am dependent upon an outside server for is something that can go wrong and allows someone else to monetize my web site.
I particularly like how this plugin uses a javascript library that puts the latex rendering burden on the client browser.
This plugin does allow serving of the required javascript from offsite, but does not require it nor is it enabled by default.
Usage is simple and easy. Resources are only expended on those pages that use latex – those that don’t have no overhead.
