This proven textbook provides an introduction to and practical applications of the basic concepts of calculus. The book's usefulness extends far beyond the classroom, as many students find that it serves as an excellent reference tool for advanced courses and graduate work. This edition contains more exercises requiring written responses, and more numerical examples and exercises. Each of these features is a result of the present-day teaching techniques, in which students are asked to contemplate the concepts more, and use technology where applicable. Calculus, 6e is ideal for students majoring in physical sciences, engineering, computer science or mathematics. As with earlier editions, the text fits a three-semester (four or five quarter) introductory calculus of one and several variables. It can also be used for a one-year course in single-variable calculus.
