The reader will understand that calculus is not all sweetness and light. There is
work to do. You absolutely have to solve problems—and think carefully. As one of
my students said, “My God, I have to read the words.” I guess that's true, and I hope
the words come to the point. The book will try not to waste your time. Its object is
not to “cover” material, but to uncover and explain it. In the end, teaching a subject
comes down to teaching a person.
