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.
