Amazon.com description: Product Description: This non-rigorous, yet accurate presentation of the applications of calculus to technologies is exceptionally student-oriented. The presentation is clear and concise, the examples are worked in great detail (enhanced by marginal annotations), and step-by-step procedures are used whenever possible. While the approach is accessible and intuitive, the author has retained the TTspiritTT of the calculus by use of historical notes, interesting asides, and informal motivations.
