Bought this for 2$ at a book sale and read it until the Integrals chapter before 12th grade. It was extremely fun to study and there were so many problems that the fundamental concepts would just get ingrained in you after solving them all. Got a grade of 98 and 96 in basic calculus in 12th grade since the lessons were just like a review. A simple to understand “essential” math book that I’ll definitely always reference back to in college. Again, there are so many problems in this book to solve to train you rigorously.
At times I loved this book, at times I hated it, but it has consumed my life for the past couple months. Overall, a good calculus text, but at times the organization and order of the chapters has seemed strange.
A fairly good textbook in the hands of a good instructor. It did unfortunately lack the integration of inverse trig functions in chapter 5, which was disappointing. I'd recommend it though to a student with a thorough instructor.
