Again I will say for the umpteenth time. This book is NO GOOD. I DON'T CARE WHAT KIND OF IMPROVEMENTS THIS LOW-QUALITY BOOK MADE.I've used the 4th edition of this low quality book and I saw the previous editions to it. I don't EVEN begin to think that this so-called new 5th addition brings anything new to the table that the calculus student can benefit from.I will speak as a pharmacy student from an accredited pharmacy school. If any professor asked me to recommend a calculus book to teach his class the one recommendation I would give to that math teacher is to "STAY AWAY FROM THIS AUTHOR AND HIS CALCULUS BOOKS". There are way too may user-friendly calculus that explain the concepts and methodology of calculus one million times better than what Stewart and his collegues can write.Stewart needs to retire from the math texbook writing business.
