-The Basics documentation section covers the basic foundations of differential and integral calculus, including derivatives, curve sketching, integrals, antiderivatives and integration techniques.

The version currently up is a summary created by Claude which has not yet been edited by me. As I go through it I will edit it carefully. Also there is no code or notebooks yet, and those will be created as I go through the text.
