About the Book

NOTE: This edition features the same content as the traditional text in a convenient, three-hole-punched, loose-leaf version. Books a la Carte also offer a great value; this format costs significantly less than a new textbook. Before purchasing, check with your instructor or review your course syllabus to ensure that you select the correct ISBN. For Books a la Carte editions that include MyLab(TM) or Mastering(TM), several versions may exist for each title--including customized versions for individual schools--and registrations are not transferable. In addition, you may need a Course ID, provided by your instructor, to register for and use MyLab or Mastering platforms.

For courses in Precalculus.

Effectively emphasizes both concept development and real-life applications

The Ratti/McWaters/Skrzypek series draws from the authors' extensive classroom experience to connect concepts while maintaining course rigor. Just-in-time review throughout Precalculus: A Right Triangle Approach, 4th Edition ensures that all students are brought to the same level before being introduced to new concepts. Numerous applications are used to help students apply the concepts and skills they learn in college algebra and trigonometry to other courses (including the physical and biological sciences, engineering, economics, and to on-the-job and everyday problem solving).

Students are given ample opportunities to think about important mathematical ideas and to practice and apply algebraic skills. Because mathematical concepts are developed thoroughly and with clearly defined terminology, students see the "why" behind those concepts--paving the way for a deeper understanding, better retention, less reliance on rote memorization, and ultimately more success.

Also available with MyLab Math.

MyLab(TM) Math is the teaching and learning platform that empowers instructors to reach every student. By combining trusted author content with digital tools and a flexible platform, MyLab Math personalizes the learning experience and improves results for each student.

NOTE: You are purchasing a standalone product; MyLab Math does not come packaged with this content.
