TeX formulas

Quarkdown natively supports TeX math equations and formulas. When rendering to HTML, this feature is powered by MathJax.

Inline

Inline formulas can be created by wrapping text between two $ symbols. Both delimiters must be preceded and followed by a whitespace (or beginning/end of the line).

Let $ \overline v = \frac {\Delta x} {\Delta t} $ be the **average velocity** of an object.

One-line block

Block formulas are usually visually centered, and can be created as with inline ones, as long as it's isolated from other inline content:

The following function is a **Fourier Transform**:

$ F(u) = \int^{+\infty}_{-\infty} f(x) e^{-i 2\pi x} dx $

Note

This syntax does not interrupt paragraphs, so make sure to space blocks properly. If the paragraph is not interrupted, the formula is recognized as inline, due to Markdown's lazy lines:

The following function is a **Fourier Transform**:
$ F(u) = \int^{+\infty}_{-\infty} f(x) e^{-i 2\pi x} dx $

Multiline block

A block formula can span over multiple lines thanks to a syntax similar to fenced code blocks, though using three $ symbols as delimiters:

$$$
f(x) =
\begin{cases}
    0 & \text{if } x = 0 \\
    1 & \text{if } x \neq 0
\end{cases}
$$$
