うまくいったよｰ。
で紹介されているスクリプトを<head>の直後に入れる。
そうすると$e^{i\pi}=-1$とlatexで書いた部分が数式に変換される。
$e^{i\pi}=-1$$\sin{x}+\tan x , \log_{10} x$
$\sin{x}+\tan x , \log_{10} x$
$ S_n=\displaystyle\sum_{k=1}^{n} (x_k)^2 $
$ S_n=\displaystyle\sum_{k=1}^{n} (x_k)^2 $
\[ I=\int_{0}^{ \frac {1}{2}} \frac{x}{\sqrt{1-x^2}} dx \]
\[I=\int_{0}^{ \frac {1}{2}} \frac{x}{\sqrt{1-x^2}} dx\]
