Github blog 수식 입력 방법
29 Jun 2018 | Equation usage목차
이 글에서는 수식 입력방식을 설명한다.
수식 입력은
inline style: $ \sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6} $
$ \sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6} $
display style: $$ \sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6} $$
로 한다.
참고: newline은 display style에서만 유효하다.
$$ \begin{eqnarray} a^2 + b^2 &=& c^2 \\ &=& 5 \end{eqnarray} $$
$$ \Delta s = \Biggl\{ \begin{matrix} A \\ B \end{matrix} $$
