Rendering math

By loading this page you’ll load a .woff2 copy of Libertinus Math, which is gigantic. I’d like to learn how to subset mathematical fonts – I don’t expect to use many exotic characters, I really just want a nice serif with matrix bars, stretchy parenthesis, maybe some Greek letters.

The markup is straight out of Pandoc’s --mathml output, so you’ll need a browser that supports MathML.

Basics of inline math

Let $x=25$. Then $\sqrt{x} = \pm 5$. Can you believe that? No way. What if $\sqrt{x} ≠ \pm 5$?

Stretchy radicals, delimiters, and matrices

Nested radicals:

$$\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{1000}}}}}}}$$

Big parens:

$$5(\frac{10\frac{x}{j}}{4})$$

Matrices:

$$\left(\begin{bmatrix} 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{bmatrix} + \begin{bmatrix} 9 & 8 & 7 \\ 6 & 5 & 4 \\ 3 & 2 & 1 \end{bmatrix} \right) = \begin{bmatrix} 10 & 10 & 10 \\ 10 & 10 & 10 \\ 10 & 10 & 10 \end{bmatrix}$$
