This brief, paperback version of the Ninth Edition of College Algebra by Lial, Hornsby, and Schneider has been specifically designed to provide a more compact and less expensive alternative to traditional textbooks; Essentials of College Algebra better meets the needs of colleges whose College Algebra courses do not include the more advanced topics covered in the longer text. Simply put, Essentials of College Algebra gives students a solid foundation in the basic functions of college algebra and their graphs, starting with a strong review of intermediate algebra concepts up front and ending with an introduction to systems of linear equations, sequences, and series. Focused on helping students develop both the conceptual understanding and the analytical skills necessary to experience success in mathematics, the authors present each mathematical topic in this text using a carefully developed learning system to actively engage students in the learning process. The book addresses the diverse needs of today's students through an open design, current figures and graphs, helpful features, careful explanations of topics, and a comprehensive package of supplements and study aids.
