One Mathematical Cat, Please! Understanding Calculus

Curious about Calculus? Want honest content, but a bit ‘slower and kinder’ than traditional Calculus books?

Like the way I explain things in Algebra I, Geometry, Algebra II, and Precalculus? Then, this book is for you.

It's a complete Calculus course. You can read it online or buy a printed version.

I call it the ‘warrior cat’ book because of the print-version cover. (You can read about these four cats in my Mathematical Cat Gallery: numbers 23, 24, 25 and 26.)

The entire book is available below.

Gone through my online curriculum through Precalculus? Then, jump right into Chapter 3.

Haven't been using my lessons? No problem. The first two chapters review essential material and introduce you to all the math language concepts you'll need.

Print Version of the ‘Warrior Cat’ Book (and Complete Solution Manual)

Calculus book main cover
Understanding Calculus
(the main text)

The PRINT version of the Warrior Cat book is for those of us who like to highlight, write in margins, feel the paper between our fingers.

Both the online and print versions include selected solutions: odd-numbered end-of-section exercises and Quick Quiz Problems.

Complete Solution Manual

For ALL the solutions, I also offer a Complete Solution Manual. It includes completely-written-out solutions to:

All the in-section exercises
All the end-of-section exercises
All the sample tests

Calculus Index Cards

I also offer a set of Calculus Index Cards. Hold the entire course in the palm of your hand!

Classic Calculus Textbooks

These are the Calculus textbooks I learned and/or taught from in my early days (before using my own materials). You can see the well-worn bindings. I even put tabs on Stewart to help me quickly turn to various sections.

$my Calculus books$

Of course, you can't (easily, at least) get the ones that I have anymore. I can't comment directly on any of the current editions (below), but all the ones I have are excellent. If you want a more traditional text, likely any of these would be a great choice.

Calculus: One and Several Variables
My fourth edition by Salas and Hille has evolved into this tenth edition with added author Etgen.
Calculus
My fourth edition by Stewart has evolved into this ninth edition with added authors Clegg and Watson.
Calculus and Analytic Geometry
My first edition by Stein has evolved into this fifth edition with added author Barcellos.
