    Math (LaTeX)

    Write inline and display equations with LaTeX, rendered live in the editor and in exports.

    inkwell renders LaTeX with KaTeX, right where you type. The raw formula comes back whenever your cursor touches it, so it’s always editable.

    Write an inline formula

    Wrap the formula in single dollar signs:

    The famous equation $E = mc^2$ changed physics.
    Renders as
    E=mc2E = mc^2

    A few rules keep prices and formulas apart:

    • No space right after the opening $ or right before the closing $.
    • The closing $ can’t be followed by a digit, so It costs $5 and $10 stays as normal text.
    • Inline math stays on one line.

    Write a display formula

    For a formula on its own line, use double dollar signs. It can run over several lines:

    $$
\int_0^1 x^2 \, dx = \frac{1}{3}
$$
    Renders as
    ∫01x2 dx=13\int_0^1 x^2 \, dx = \frac{1}{3}

    Use a math code block

    If a formula is long, or contains $ characters, put it in a fenced block. inkwell accepts math, latex, tex and katex as the block’s language:

    ```math
\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}
```
    Renders as
    ∑n=1∞1n2=π26\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}

    More examples to copy

    Write this Get this
    $\sqrt{a^2 + b^2}$ the Pythagorean hypotenuse
    $x_{i}^{2}$ subscripts and superscripts
    $\alpha + \beta = \gamma$ Greek letters
    $$\begin{bmatrix} 1 & 0 \\ 0 & 1 \end{bmatrix}$$ a 2×2 matrix
    Renders as
    [1001]\begin{bmatrix} 1 & 0 \\ 0 & 1 \end{bmatrix}

    Good to know

    • Math inside inline code or code blocks is never rendered, so you can show the dollar syntax itself.
    • A formula KaTeX can’t read is shown as text instead of breaking the note.
    • Rendered math and its formatting carry over when you export to HTML or PDF.
    • Math works in Normal mode and in the Markdown-mode preview.
