Intermediate algebra structure and use | ||||||||

Autor: Raymond A. Barnett, Thomas J. Kearns AnotaceThis new edition aims to bridge the student's first experience manipulating algebraic expressions to the more abstract skills they will develop in later courses. Students begin with a review of topics from elementary algebra. Inequalities take on a greater role and complex numbers are introduced. After the review and extension of the quadratic equation, the course takes on a more abstract and graphing direction, dealing with two variables, relations and functions and systems of equations and inequalities. Each concept is illustrated with an example, followed by a parallel problem wth an answer. The book contains many realistic applications from the physical sciences, business and economics and social sciences, and chapter review sections include a summary of the important terms and symbols.
