膠登打math symbols入門
e個post會假定你裝左khinchin巴打個plugin, 如果無裝往後內容你只會睇到係一堆code.
plugin條link: https://hkgalden.com/view/4350
e個post只會講D最基本野(中學應該夠用), 想學多d o既請去http://martinkeefe.com/math/mathjax5.
個plugin唔會影響你正常打文, 但如果你用兩個dollar sign一前一後夾住d字就會有影響, 被夾o個d字會變斜體同埋你打o個d code會變math symbols.
e.g. a+b變$a+b$, hi變$hi$.
如果你想打a x b 你就咁括住佢o既話就會變左咁$axb$, e個時候你就要打code去表達個乘號. 你可以打
a \times b $a\times b$或 a\cdot b $a\cdot b$.
常見o既符號code可以o係e個表搵到: http://martinkeefe.com/math/mathjax3
譬如你想打alpha出黎,就用dollar sign括住\alpha (會出$\alpha$), 基本上D符號就係咁打出黎. 下面會講d基本operations.

冇得preview好煩
MathJax 那方面是有preview 版, 皆因這個不是admin 放下去, 所以請去 以下網頁做preview

`|x|={ (x), (-x) :}`
$\begin{CD}
A @>>> B @>{\text{very long label}}>> C \\
@VVV @VVV @VVV \\
D @>>> E @>{\phantom{\text{very long label}}}>> F
\end{CD}$
A @>>> B @>{\text{very long label}}>> C \\
@VVV @VVV @VVV \\
D @>>> E @>{\phantom{\text{very long label}}}>> F
\end{CD}$
暫時對數學符號 大過 或 細過, 都是用code 比較穩妥
`A le B text{ or } A ge B`
`A gt B text{ or } A lt B`
`A le B text{ or } A ge B`
`A gt B text{ or } A lt B`
In equation \eqref{eq:sample}, we find the value of an
interesting integral:
\begin{equation}
\int_0^\infty \frac{x^3}{e^x-1}\,dx = \frac{\pi^4}{15}
\label{eq:sample}
\end{equation}
