When I decided to pursue my engineering degree I discovered that I needed to take calculus-1 and 2. I had already taken calculus-1, but that was over 7 years ago. I then realized I'd "FORGOTTEN CALCULUS". This book was for me, literally. Anyone who desires a calculus review, or would like to learn on their own, should pick up this text. A basic knowledge of algebra is all that is really required. The algebraic review, in the first 9 lessons (out of 28), makes the transition to calculus a breeze. The author is careful to not take anything for granted, and never goes off on tangents (ha ha). The worked out examples have a natural progression that makes sense of the entire problem, not just the answer. The problems and exercises, which you work out yourself, are very comprehensive and appropriate. All the answers are given so that you can check your work. This book rocks!
