I don't like to complain about books because someone went to the effort to write it but this book is horrible.
First the book provides very little explanation before diving into a problem and then steps are skipped, the author noted that something is "Obvious" and then the answer is given and the reader is left wondering what happened.
Then there are problems for the person to solve BUT there is no answer, yes, a self teaching guide without answers for some of the problems.
This is NOT the book to get if you are wanting to learn Calculus, review Calculus or teach Calculus.
Its a good thing that Isaac Newton was one of the creators of Calculus because if he would have had this book to start with much of modern science would have been delayed decades for someone else to come along because Newton would have given up on math
