LaTeX on Blogger

It works!
現在在文章中用 $ 夾住式子就會去 render 成 LaTeX 語法了

範例:
用$夾住
K=F_k\supset F_{k-1} \supset\ldots\supset F_1\supset F_0 = \mathbb{Q}

就會出現
$K=F_k\supset F_{k-1} \supset\ldots\supset F_1\supset F_0 = \mathbb{Q}$

可以弄得很複雜 如:
\[ \setlength{\unitlength}{1mm}\begin{picture}(60, 40)\put(30, 20){\vector(1, 0){30}}\put(30, 20){\vector(4, 1){20}}\put(30, 20){\vector(3, 1){25}}\put(30, 20){\vector(2, 1){30}}\put(30, 20){\vector(1, 2){10}}\thicklines\put(30, 20){\vector(-4, 1){30}}\put(30, 20){\vector(-1, 4){5}}\thinlines\put(30, 20){\vector(-1, -1){5}}\put(30, 20){\vector(-1, -4){5}}\end{picture}\]

\[ \begin{aligned}K=F_k & \vartriangleright & F_{k-1} &\vartriangleright &\ldots & \vartriangleright & F_1 & \vartriangleright& F_0 =\mathbb{Q} & & \textrm{where} |G_i:G_{i+1}| = |F_{i+1}:F_i|\\ \updownarrow & & \updownarrow & & \updownarrow & &\updownarrow & &\updownarrow & & \textrm{i.e. } G_i/G_{i+1} \simeq \mathbb{Z}_{p_i} \textrm{ Abelian }\\ \{1\}=G_k& \vartriangleleft & G_{k-1} & \vartriangleleft & \ldots & \vartriangleleft & G_1 & \vartriangleleft & G_0 = G & & \Rightarrow f \textrm{makes that} G \textrm{is solvable} \end{aligned} \]



\[\begin{bmatrix}a&b&c\\d&e&f\\g&h&i\end{bmatrix}\]
只是太寬的圖在blog上會很醜 xPPP

要安裝時可以參見右側欄的  gadet $\sqrt{\frac{x}{y}}$
不過要把它的 javascript 改貼成:

<script src="http://watchmath.com/cgi-bin/mathtex3.js?hl=en&amp;gda=R9ZVlD4AAABbAsbN4i7hi2ZFNZpVWCi9LFztQtuc529xoR6FBh351sAOXLBpscdVgFPClVlUxUzjsKXVs-X7bdXZc5buSfmx" type="text/javascript"></script>
<script type="text/javascript">window.mathPreamble =
 '\\usepackage[usenames]{color}\\color{} \\gammacorrection{1.3}\\png \\normal ';replaceMath( document.body );</script>

因為它的新版 js 掛掉了 (然後原作者好像沒有要維護的意思...) 要把連結改回舊的
也因此不支緣 newcommand 所以在 preamble 那邊要修改
