Algebra and Trigonometry: Enhanced with Graphing Utilities, 9th Edition eBook

The proven approach of Sullivan and Sullivan, highly experienced math instructors, focuses you on the fundamental skills you’ll need to succeed in your course: prepare for class, practice with homework, and review the concepts. Algebra and Trigonometry: Enhanced with Graphing Utilities fully integrates graphing utilities into topics, allowing you to explore mathematical concepts and encounter ideas usually studied in later courses. Many examples show solutions using algebra side by side with graphing techniques.

Along with all college algebra material, it develops the trigonometric functions using a right triangle approach and shows how that approach is related to the unit circle approach. After completing this text, you will be more prepared for finite mathematics, business calculus, and engineering calculus.

The 9th Edition is revised and refined throughout, with:

• Updated Desmos and screen captures as well as TI-84 Plus CE screens
• Updated exercise sets with timely and relevant scenarios
• A new Highlighting Contemporary Mathematicians feature
• And much more
