To add Latex code in HTML website, there are two ways,
- Simple way to add Latex code is using HTML image tag(for more info visit codecogs):
<img src="http://latex.codecogs.com/gif.latex?1+sin(x)" border="0"/>
- Using MathJax CDN:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>MathJax example</title>
<script type="text/javascript" async
src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js?config=TeX-MML-AM_CHTML">
</script>
</head>
<body>
<p>
When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
