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.
