# LaTeX math

Renders a block mathematical equation written in LaTeX, centred on its own line in the page.

When a page needs a real equation rather than a picture of one - a formula in a spec, a derivation in a research note, a bit of statistics in a report - this macro renders LaTeX with KaTeX so the maths is sharp at any zoom and stays editable as text. You write the source in a plain textarea, or switch to the Live tab for a visual equation editor if you do not want to remember the syntax. If your site has Capable AI enabled, a Generate button lets you describe the equation in words and have the LaTeX written for you. Use it for standalone display equations; for a symbol inside a sentence, use LaTeX math inline instead.

## See it

Every example below is a real macro on this page, not a screenshot, and each one is a configuration taken from a page somebody actually built. Open this page in the editor to see how any of them is set up.

### Left, 21px

x2+y2=1y=1−x2\\begin{align\*} x^2 + y^2 &= 1 \\\\ y &= \\sqrt{1 - x^2} \\end{align\*}x2+y2y​\=1\=1−x2​​

### Center, 21px

x2+y2=1y=1−x2\\begin{align\*} x^2 + y^2 &= 1 \\\\ y &= \\sqrt{1 - x^2} \\end{align\*}x2+y2y​\=1\=1−x2​​

### Center, 21px (2)

C=A+BD=A⋅B\\begin{align\*} C &= A + B \\\\ D &= A \\cdot B \\end{align\*}CD​\=A+B\=A⋅B​

## Settings

![The LaTeX macro's insert window. Two centred equations, x squared plus y squared equals 1 and y equals the square root of 1 minus x squared, preview on the left. The configuration panel on the right h](https://help.gocapable.com/images/6f81f10b-8ab5-4c50-b2bf-1658445e3aed.webp)

The equation is written as LaTeX on the right and drawn on the left as you type, with alignment and font size underneath it.

| Latex Equation  | Any LaTeX. Two editing modes in the panel: Text (plain textarea, 5 rows) and Live (a visual equation editor loaded on demand). Rendered with \`throwOnError: false\`, so a broken expression paints in red (#cc0000) rather than blanking the macro. Leading and trailing \`$\` delimiters are stripped before rendering, so pasting \`$$x^2$$\` works. | The equation itself. Empty renders the text "Invalid LaTeX equation".
