Lorem Ipsum — Rendering Test

Sandbox post

A throwaway post to test Markdown + math rendering. Safe to delete.

inline code, bold, italic, strike, and a link.

def hello(name: str) -> None:
    print(f"hello, {name}")

Callout

Obsidian-style callouts render too.

Math (KaTeX grammar coverage)

Inline: $E=m{c}^2$, $\alpha +\beta =\gamma$, $x\in {\mathbb{R}}^n$, $\left(\genfrac{}{}{0ex}{}{n}{k}\right)$.

Display, integral & fraction:

$${\int }_0^{\infty }{e}^{-x^2}dx=\frac{\sqrt{\pi }}{2}$$

Aligned (Maxwell):

$$\begin{array}{rl}\nabla \cdot \mathbf{E}& =\frac{\rho }{{\epsilon }_0}\\ \nabla \times \mathbf{B}& ={\mu }_0\mathbf{J}+{\mu }_0{\epsilon }_0\frac{\partial \mathbf{E}}{\partial t}\end{array}$$

Matrix & cases:

$$A=\left[\begin{array}{cc}1& 2\\ 3& 4\end{array}\right],f(x)=\{\begin{array}{ll}{x}^2& x\ge 0\\ -x& x<0\end{array}$$

Sums & limits:

$$\sum _{k=1}^{n}k=\frac{n(n+1)}{2},\underset{x\to 0}{\lim }\frac{\sin x}{x}=1$$
