Which is the best book on calculus?

Answer 1

In my opinion, the best one out there is "The Humongous Book of Calculus Problems", by W. Michael Kelley. It contains one thousand questions from warm-up algebra to second year calculus. With each question he walks you through solving it, explaining why it works and providing a battery of explanations and tips. I learned a ~lot~ from that book, enjoyed it thoroughly, and recommend it to anyone who wants to learn calculus or take a refresher.
