# 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
KaTeX typesetting
Inline $...$ and display $$...$$ math render to clean, precise equations.
No LaTeX engine
Skip the TeX Live download — math renders in your browser instantly.
Mix prose and math
Combine narrative, tables, code and equations in one document.
100% private
Conversion runs entirely in your browser. Nothing is uploaded — your content never touches a server.
Math without the toolchain
Producing math PDFs with Pandoc means installing a full LaTeX engine — often several gigabytes. Here, KaTeX renders your equations directly in the browser, so you get publication-quality math without any setup.
For notes, problem sets and papers
Whether you're writing lecture notes, a homework set or a short paper, you can interleave display equations, inline symbols, matrices and aligned expressions with the rest of your Markdown and export it all at once.
Frequently asked questions
What math syntax is supported?
LaTeX-style math via KaTeX: inline with $...$ and display blocks with $$...$$, including matrices and aligned equations.
Do I need to install LaTeX?
No. KaTeX renders entirely in your browser, so there's no TeX Live or MiKTeX install required.
Is the math selectable in the PDF?
Equations render as crisp markup-based output that prints sharply in the exported PDF.
