Math Tests

You can do inline math: \(e^{i\pi} = -1\) and display style math:

\[a^2 + b^2 = c^2\]

\[\begin{split}\begin{equation} f(x) = \begin{cases} x & \text{if }x < 0 \\ x + 1 & \text{if }x \ge 0 \\ \end{cases} \end{equation}\end{split}\]

\[\begin{split}\left[\begin{array}{cc|c} \columncolor[rgb]{0, 1, 1} 1 & 1 & -1 \\ 2 & 3 & 0 \\ \end{array}\right]\end{split}\]

Here’s one option for a div with an id, but you need to typeset onload:

\begin{split}\left[\begin{array}{cc|c} \columncolor[rgb]{0, 1, 1} 1 & 2 & 3 \\ 4 & 5 & 6 \\ \end{array}\right]\end{split}

This one will be typeset on its own, and it can have an id via :name:.

\[\begin{split}\begin{split}\left[\begin{array}{cc|c} \columncolor[rgb]{0, 1, 1} 1 & 2 & 3 \\ 4 & 5 & 6 \\ \end{array}\right]\end{split}\end{split}\]

MathJax doesn’t like bordermatrix, so here’s a way of labeling:

\[\begin{split}\begin{matrix} & \begin{matrix}A&C&G&T\end{matrix} \\\\ \begin{matrix}A\\\\C\\\\G\\\\T\end{matrix} & \begin{pmatrix}1&2&3&4\\\\3&4&5&6\\\\3&4&5&6\\\\3&4&5&6\end{pmatrix}\\\\ \end{matrix}\end{split}\]
