About Trig Identities Practice Workbook With Answers

Product Description This trigonometry workbook focuses on trig identities. The majority of the exercises let you derive a variety of trig identities by following similar examples. If you get stuck, helpful hints in the back of the book help walk you through the solution. Other exercises include applications, such as how to find the tangent of 15 degrees without a calculator or how to apply trig identities to solve equations. This book also serves as a handy list of numerous trig identities organized by topic. The answer to every problem can be found at the back of the book. The author, Chris McMullen, Ph.D., has over twenty years of experience teaching math skills to physics students. He prepared this workbook of the Improve Your Math Fluency series to share his knowledge of trig identities. From the Author Is this book about deriving trig identities or how to apply them? Both. Nearly every chapter shows how to derive one or more trig identities and includes problems that involve deriving trig identities (with hints, notes, and answers in the back to aid with this). Some chapters also include examples and problems that involve applying trig identities, such as how to solve an equation that involves trig functions, how to find the sine of 15°, or how to apply the law of sines or the law of cosines to determine an unknown side or angle in an acute or obtuse triangle. The last chapter is specifically devoted to applications of trig identities. Which kinds of trig identities are covered in this book? Comprehensive coverage includes Pythagorean identities, odd/even function identities, angle sum formulas, double angle formulas, half-angle formulas, triple angle formulas, power reductions formulas, sum-to-product identities, product-to-sum identities, angle shifting identities, the law of sines, the law of cosines, and inverse function identities. Will this book be useful even after the student has finished using it? Absolutely. Several handy trig identities are tabulated on the back cover for easy access. The book itself serves as a handbook of trig identities with a concise revise of each topic in each chapter. Does this book include answers? Yes. The answer to every problem is tabulated at the back of the book, along with handy hints, notes, and tips. Does this book work out examples? Yes. Each example serves as a handy guide for how to solve similar problems. What are the qualifications and experience of the author? Chris McMullen earned a Ph.D. in physics from Oklahoma State University and has over 20 years of experiencing teaching trigonometry skills to physics students. Does the author have any other trigonometry books? Trigonometry Essentials Practice Workbook with Answers. Which of the author's books should a student buy after using this trigonometry workbook? The author's next book is Logarithms and Exponentials Essential Skills Practice Workbook (with answers).
