Math#

Write TeX between dollar signs. Sumi typesets it with a bundled copy of KaTeX, loaded only on pages that contain a formula.

Inline formulas#

Euler's identity, $e^{i\pi} + 1 = 0$, links five constants.

Euler's identity, $e^{i\pi} + 1 = 0$ , links five constants.

A dollar sign followed by a space, or preceded by a letter or digit, is not math — so prices such as $5 or $10 stay as written. Escape a literal dollar sign as \$.

Display formulas#

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

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

Multi-line environments work too:

\begin{aligned} \nabla \cdot \mathbf{E} &= \frac{\rho}{\varepsilon_0} \\ \nabla \times \mathbf{B} &= \mu_0 \mathbf{J} + \mu_0 \varepsilon_0 \frac{\partial \mathbf{E}}{\partial t} \end{aligned}

Compatibility#

If pymdownx.arithmatex is configured with generic: true, Sumi renders its output with the same KaTeX and turns its own $ parsing off. To disable math entirely, set math: false on the plugin.
