I was required to buy this book because of my Calc II class, and I must say it was rather horrible. As my teacher was incompetent and simply took samples out of the book and did them on the board, I found myself relying on teaching myself the material out of the book. Unfortunately, the amount of explanation in the text is... minimal, at best. It usually just says "This is what you do, and it works because it's MATH." The examples skip a fair number of algebraic steps--great, if you remember every bit of your middle and high school math classes, but very confusing if you forget anything. I ended up failing the class because I couldn't learn an adequate amount out of this book.I used a different book for Calc I, and this can't hold a candle to it. If I was unsure of something, I could read the start of a chapter and understand it. This book, more often than not, leaves me more confused than when I started.
