[Tutorial] Step by step teaches you how to use Mathjax3.0 (Part 1)

First of all, in order for Markdown to be able to parse LaTeX mathematical expressions, under normal circumstances, we need to import the MathJax plugin to work:

<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>

Then you try to output some formulas.

Example:

When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are
  \[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]

Mathjax:

When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are
  \[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]

Okay, in fact, I have to show it in Code blocks, otherwise it will be parsed into formulas. The following content is also for this reason, I put them in the code block.


Let me tell you how to use these symbols in the first step.

Code:

\(a \ne 0\)

Mathjax:

\(a \ne 0\)

As you can see, the drawing of a mathematical formula starts with parentheses, and "\" is an escape character.

In other words, you must start with "\(" or "\[" and end with "\)" or "\]".

The "{" and "\{" will not be escaped and will only be output normally.

  • "(" will only have one line, and it looks very small if you have fractions in it.
  • "[" will use at least 2 lines to show your formula, and your formula will be centered and the size is more appropriate. We usually use "\[" to start our formula.
  • "{" will not have any response, no matter whether you use the "\" escape character or not.


Okay, you have learned the basic display method. The next blog, I will tell you another display method.
