About this book :-
"Trigonometry" by "Ted?Sundstrom" and "Steven?Schlicker" is a practical, student-friendly textbook designed for first-year college trigonometry courses. This book emphasizes "active learning", encouraging students to engage with exercises and examples rather than passively reading. It introduces concepts with "beginning activities", guiding learners through foundational ideas before tackling complex problems. Short "progress checks" throughout each chapter help students monitor their understanding and strengthen retention. The textbook covers all essential "trigonometry topics", including functions, graphs, triangles, identities, equations, and polar coordinates. Its approach combines traditional explanations with "interactive tools", like GeoGebra applets, to support visual learning and problem-solving. Conceptual understanding is prioritized, making it easier for students to apply techniques in real-world and mathematical contexts. The exercises range from straightforward practice problems to challenging applications, offering a well-rounded learning experience. Sundstrom and Schlicker’s book stands out for its clarity, structured approach, and focus on "concept mastery". Freely available under a Creative Commons license, it is accessible to a wide audience and supports "self-paced learning". Whether used in classrooms or for independent study, it builds a strong foundation in trigonometry, equipping students with the skills and confidence to succeed in higher-level mathematics.
