LaTeX Math Support

Write math equations in cards using LaTeX. Formulas for your scientific, academic, and engineering papers and projects can live right alongside where you think through problems and collect research.

Enclose your LaTeX between triple backticks to make a codeblock, then use the code language button on the card to select latex.

You can also start the code block with latex or tex to skip the language picker step:

```latex
x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
```

More Examples

Fractions, roots, and exponents

e^{i\pi} + 1 = 0

Integrals and sums

\int_0^\infty e^{-x^2} \, dx = \frac{\sqrt{\pi}}{2}

Multi-line equations

\begin{aligned}
(a + b)^2 &= (a + b)(a + b) \\
&= a^2 + 2ab + b^2
\end{aligned}

Matrices

A = \begin{pmatrix} a & b \\ c & d \end{pmatrix}

LaTeX Pro-Tips

• each code block is rendered as a single equation, use {aligned} for multiple lines
• use \text{} to write regular words inside an equation
• if part of your equation is shown in red, that command has a typo or isn’t supported
• use the copy button on the card to copy the original LaTeX code
• only LaTeX math is supported, not document commands like \section or \usepackage
