# Calculus Notes
## The Fundamental Theorem
If $f$ is continuous on $[a, b]$, then
$$
\int_a^b f(x)\,dx = F(b) - F(a)
$$
where $F$ is any antiderivative of $f$.
## A Gaussian integral
$$
\int_{-\infty}^{\infty} e^{-x^2}\,dx = \sqrt{\pi}
$$
Inline math works too: the area of a circle is $A = \pi r^2$, and Euler's
identity $e^{i\pi} + 1 = 0$ ties together five constants.
## A small matrix
$$
\begin{bmatrix} a & b \\ c & d \end{bmatrix}
\begin{bmatrix} x \\ y \end{bmatrix}
=
\begin{bmatrix} ax + by \\ cx + dy \end{bmatrix}
$$
Key Features
Inline & display math
$...$ for inline and $$...$$ for display equations, including matrices and alignments.
No TeX install
KaTeX renders in the browser — no multi-gigabyte LaTeX distribution needed.

Combine math with tables, code and diagrams in a single export.
100% private
Conversion runs entirely in your browser. Nothing is uploaded — your content never touches a server.
LaTeX math, zero setup
You don't need a full LaTeX toolchain to get great-looking equations. Write LaTeX-style math in your Markdown and KaTeX typesets it instantly in the preview and the PDF — ideal for notes, problem sets and short papers.
From symbols to full equations
Inline symbols like $\alpha$ sit naturally in a sentence, while display blocks handle integrals, sums, matrices and aligned multi-line derivations.
Frequently asked questions
What math syntax works?
LaTeX-style math via KaTeX — inline with $...$ and display with $$...$$, including matrices and aligned equations.
Do I need to install LaTeX?
No. KaTeX runs in your browser, so there's no TeX Live or MiKTeX to install.
Can I combine math with diagrams?
Yes — math, Mermaid diagrams, tables and code can all live in the same document.
