Math environment Syntax testing

Inline Math should work with $$ $\frac{x+y}{y}$ but not \( (\frac{x+y}{y})

Use $$ on separate lines:

Use $$ on the same line: $\frac{-b \pm \sqrt{b^2-4ac}}{2a}$

Use $$ on separate lines:

Use $$ on the same line: $E=mc^2$

Some Tex Functions

$k \times k$, $n \times 2$, $2 \times n$, $\times$

$x \cdot y$, $\cdot$

Escaped Math environments

In the following examples no math environments should render:

a $5, a $10 and a $100 Bill.

Testing \newcommand

For all $x$ and $y$ in $\mathbb{R}^k$ it is true that $\newcommand{sca}[1]{\langle #1 \rangle} |\sca{x,y}|^2 \le \sca{x,x} \cdot \sca{y,y},$

\newcommand{\scalong}[1]{(#1_1,\dots,#1_k)}

where $\sca{\cdot,\cdot}$ denotes the inner product $\sca{\scalong{x}, \scalong{x}} = \sum_{i=1}^k x_i y_i$.

$\newcommand{\scalong}[1]{(#1_1,\dots,#1_k)}$where $\sca{\cdot,\cdot}$ denotes the inner product $\sca{\scalong{x}, \scalong{x}} = \sum_{i=1}^k x_i y_i$.

Testing several math fonts $p(\mathbf{m}) \sim \mathcal{N}(\mathbf{m}) e^{-\sum_{i} \beta_i m_i}$

Notice below that the $$-separated display math doesn’t have a blank line before and after (i.e. in an actual $\LaTeX$ document it wouldn’t be placed in a separate paragraph):

The characteristic polynomial $\chi(\lambda)$ of the $3 \times 3$ matrix
    $\left( \begin{array}{ccc} a & b & c \\ d & e & f \\ g & h & i \end{array} \right)$
is given by the formula
    $\chi(\lambda) = \left| \begin{array}{ccc} \lambda - a & -b & -c \\ -d & \lambda - e & -f \\ -g & -h & \lambda - i \end{array} \right|.$

This is a long line: $\chi(\lambda) = a e i-a e \lambda -a f h-a i \lambda +a \lambda ^2-b d i+b d \lambda +b f g+c d h-c e g+c g \lambda -e i \lambda +e \lambda ^2+f h \lambda +i \lambda ^2-\lambda ^3$

Does it work in different MD elements?

In Tables

The following doesn’t work (it only works with Pandoc)

| Left-Aligned | Center Aligned | Right Aligned | | :———— |:—————:| —–:| | $a+b$ | some wordy text | $1600 | | | $A=\mathbf{A}=\underline{A}=\begin{pmatrix} a_{11} & a_{12} & \cdots & a_{1n}\\ a_{21} & a_{22} & \cdots & a_{2n}\\ \vdots & \vdots & & \vdots\\ a_{m1} & a_{m2} & \cdots & a_{mn}\\ \end{pmatrix} = (a_{ij})$ | $12 | | | | $1 |
