Math Formulas

Tydora renders math with KaTeX, and you can write LaTeX formulas inline or as a block.

Note

Formula rendering is on by default. Tydora uses KaTeX only — there is no MathJax engine to switch to.

Inline Formulas

Wrap the formula in single dollar signs $ ... $ :

The mass–energy relation $E=mc^2$ is fundamental to physics.

Rendered: The mass–energy relation $E=mc^2$ is fundamental to physics.

Wrap the formula in double dollar signs $$ ... $$ and it takes its own centered line:

$$
\sum_{i=1}^{n} i = \frac{n(n+1)}{2}
$$

In live preview mode, click a rendered formula to open the formula dialog and preview as you type:

Typing LaTeX shows the rendered result immediately in the dialog
Syntax errors are reported without affecting the document
You can also open a blank dialog via the right-click menu "Insert" → "Formula Block", then confirm to insert a block formula

For complex formulas, prefer the dialog over hand-writing — the preview catches unbalanced braces immediately.

$x^2$        → superscript
$H_2O$       → subscript
$x_i^{2n}$   → combined

$\frac{a}{b}$

$\sqrt{x}$       → square root
$\sqrt[n]{x}$    → nth root

$\sum_{i=1}^{n}$   → summation
$\int_{a}^{b}$     → integral
$\prod_{i=1}^{n}$  → product

$\alpha$ $\beta$ $\gamma$ $\delta$
$\pi$ $\sigma$ $\omega$ $\theta$

$$
\begin{bmatrix}
1 & 2 \\
3 & 4
\end{bmatrix}
$$

$$
\begin{aligned}
a &= b + c \\
  &= d + e
\end{aligned}
$$

Inline formulas must be written as $...$ ; block formulas as $$...$$ on their own lines
Wrap multi-character subscripts in braces: $x_{ij}$ , not $x_ij$
Don't omit backslash commands such as \frac and \sum
If a formula errors under KaTeX, it likely uses macros from a package KaTeX doesn't implement — rewrite it with equivalent basic syntax

Tip

Markdown superscript / subscript syntax (X^2^, H~2~O) does not render in Tydora. For math, always use formula syntax.
