## What it is
An Infinitely Large Napkin is Evan Chen's open-source LaTeX textbook providing a light, self-contained introduction to higher mathematics from undergraduate to first-year graduate topics. This repository contains the TeX source files compiled into a freely available PDF.

## Use cases
- learn higher math from undergraduate to graduate level
- get a bird's-eye overview of many math fields
- find a free open math textbook
- study math beyond pop-science books with precise definitions
- contribute corrections or new chapters to a math text
- find practice problems with community solutions

## When to choose
- you want a broad, readable survey of higher mathematics
- you already have proof experience and want intuition over rigor
- you prefer free, community-maintained learning material

## When to avoid
- you need a rigorous, fully detailed treatment with complete proofs
- you are a complete beginner with no proof experience
- you need a formal reference for a single specialized subject

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, markdown
- domain: mathematics, education, tutorials
- platform: cross-platform
- tags: latex, textbook, mathematics, open-textbook, tex
