This text offers a comprehensive presentation of the mathematics required to tackle problems in economic analysis. To give a better understanding of the mathematical concepts, the text follows the logic of the development of mathematics rather than that of an economics course. The only prerequisite is high school algebra, but the book goes on to cover all the mathematics needed for undergraduate economics. It is also a useful reference for graduate students. After a review of the fundamentals of sets, numbers, and functions, the book covers limits and continuity, the calculus of functions of one variable, linear algebra, multivariate calculus, and dynamics. To develop the student's problem-solving skills, the book works through a large number of examples and economic applications. This streamlined third edition offers an array of new and updated examples. [Some of the lengthier proofs and examples have been moved to the book's Web site. This combination of formats allows the authors to add content without expanding the physical size of the book. The book and the Web material are integral to each other; examples and figures on the Web are cross-referenced in the text. A student solutions manual will be available in e-book form. Instructors will be able to access online instructor's material that includes Power Point slides.
