Markdown syntax -- Formula

Recorded in Tencent cloud markdown The syntax for writing formulas .

Common variable symbols

To display as a symbol, you need to add... Before and after the content `$, $ Formula content $

\alpha\alpha

\beta\beta

\gamma\gama

\delta\gama

\epsilon\epsilon

\varepsilon\varepsilon

\eta \eta

\theta\theta

\pi \pi

\phi\phi

\psi \psi

\omega \omega

\sigma\sigma

\tau\tau

\lambda \lambda

\mu\mu

\theta\theta

\pi \pi

\phi\phi

\psi \psi

\omega\omega

\sigma\sigma

\tau\tau

\lambda\lambda

\mu\mu

Capital letters correspond to capital pairs .

I was going to make it in tabular form , However, inserting formulas into tables in Tencent's cloud editor is not normal ..

Formula wrap ：\\

Formula block ：（& alignment ,\ Line break ,tag Formula number ）

`$\begin{split}

& The formula 1 \

& The formula 2 \

\end{split} \tag{1}$`

\begin{split} & The formula 1 \\ & The formula 2 \\ \end{split} \tag{1}

Curly braces ：

`$\begin{cases}

case1\\

case2

\end{cases}$`

A=\begin{cases} 0& \text{k=0}\\ 1& \text{k!=0} \end{cases}
