Trigonometry: A Unit Circle Approach 9th Edition PDF Download Ebook. Michael Sullivan focuses students on the fundamental skills they need for the course: preparing for class, practicing with homework, and reviewing the concepts. This text has evolved to meet today’s course needs, building on these hallmarks by integrating projects and other interactive learning tools for use in the classroom or online.

This text begins all sections to prepare students for the topics ahead. Preparing for This Section lists previously learned concepts that will be useful in the section ahead. Page references are included for easy review. Now Work "Are You Prepared?" problems support the Preparing for This Section feature, allowing students to check that they are ready to proceed to the section ahead or if they need to turn back for further review. These problems appear at the start of each exercise set.

New Internet-based Chapter Projects apply skills to real-world problems and are accompanied by assignable MathXL exercises to make it easier to incorporate these projects into the course. In addition, a variety of new exercise types, Showcase Examples, and video tutorials for MathXL exercises give instructors even more flexibility, while helping students build their conceptual understanding.

Concepts and Vocabulary questions are fill-in the-blank and true/false items that assess students’ understanding of key definitions and concepts. These have been written to serve as reading quizzes and are now assignable in MyMathLab® and MathXL®. Skill Building problems provide straightforward practice, are organized by difficulty, and are correlated to section examples.

Graphical problems use graphs in a variety of ways, supplementing analytical understanding with graphical understanding. Now Work problems, marked by a yellow icon in the exercise set, correspond to a related example within the section. If students get stuck while doing their homework, they can look for the closest Now Work problem and refer back to the related example.
