A Basic Approach to Precalculus Trigonometry: Preparing to Succeed in Calculus provides a concise, accessible introduction to trigonometry for high school and first-year college and university students. The book builds up the skill sets needed to succeed in college and university calculus courses. The material is organized into five chapters: rational functions; trigonometric functions; trigonometric identities and equations; applications of trigonometric functions, and sequences and series. Within each section all math terms are well-defined before instruction. The instruction is then organized into manageable, easily assimilated chunks with example problems and their solutions, followed by practice opportunities. Once an instructional unit is completed, all steps are listed in box format to help students organize and remember information. A Basic Approach to Precalculus Trigonometry breaks mathematical concepts down into steps that students can approach with ease and practice with confidence. The book prepares students who are new to trigonometry to succeed in more advanced courses.
