LaTeX

typesetting:

• engine: KaTeX
• phase: build time
• scope: math expressions

Syntax

Block math

syntax:

• delimiter: $$
• placement: opening and closing delimiters on dedicated lines

source:

$$
f(x) = \int_{-\infty}^\infty
    f\hat(\xi),e^{2 \pi i \xi x}
    \,d\xi
$$

output:

$$f(x)={\int }_{-\infty }^{\infty }f\widehat{(}\xi ),e^{2\pi i\xi x}d\xi$$

aligned_equations:

$$\begin{array}{rl}a& =b+c\\ & =e+f\end{array}$$

matrix:

$$\left[\begin{array}{ccc}1& 2& 3\\ a& b& c\end{array}\right]$$

annotated_derivation:

$$\begin{array}{rll}E\psi & =H\psi & \text{Expanding the Hamiltonian Operator}\\ & =-\frac{{\hslash }^2}{2m}\frac{{\partial }^2}{\partial x^2}\psi +\frac{1}{2}m\omega x^2\psi & \text{Using the ansatz ψ(x)=e−kx2f(x), hoping to cancel the x2 term}\\ & =-\frac{{\hslash }^2}{2m}[4k^2{x}^{2}f(x)+2(-2kx)f^{\prime }(x)+f^{\prime \prime }(x)]e^{-k{x}^2}+\frac{1}{2}m\omega x^{2}f(x)e^{-k{x}^2}& \text{Removing the e−kx2 term from both sides}\\ & \Downarrow & \\ Ef(x)& =-\frac{{\hslash }^2}{2m}[4k^2{x}^{2}f(x)-4kx{f}^{\prime }(x)+f^{\prime \prime }(x)]+\frac{1}{2}m\omega x^{2}f(x)& \text{Choosing k=2imℏω to cancel the x2 term, via −2mℏ24k2=21mω}\\ & =-\frac{{\hslash }^2}{2m}[-4kx{f}^{\prime }(x)+f^{\prime \prime }(x)]& \end{array}$$

Warn

$$ block delimiters must occupy dedicated lines due to remark-math limitations.

Inline math

syntax:

• delimiter: single $ example:
• source: $e^{i\pi} = -1$
• output: $e^{i\pi }=-1$

Escaping $

rule:

• escape literal dollar signs as \$ to prevent math parsing examples:
• incorrect: I have $1 and you have $2
• correct_source: I have \$1 and you have \$2
• output: I have $1 and you have $2
