[Author here] We hear you! Here's a similar book for Calculus: https://github.com/the-little-book-of/calculus

In this book, I cover Functions, Derivatives, Integrals, Multivariable Calculus, and Infinite Processes. In addition, I've included appendices with sketch proofs and applications to Physics, Probability and Statistics, and Computer Science.

It is not visible to the public, I think.

Serge Lang's "Short Calculus" is clear and concise, efficiently covering the basics in ~170 pages instead of hundreds of pages like some books. It then has a few more chapters going into a bit more depth but on topics that are also essential if you want to take things further
