Trigonometry: From Theory to Application introduces the basics of trigonometry and key areas of practice, fully considering in straightforward, pragmatic terms the characterization of triangles, coordinate transport, and coordinate systems, with emphasis on interpreting key concepts and applying them. This book begins with a review of basic trigonometric functions and their properties, and moves on to trigonometric identities, equations, and practical applications. Each chapter is interconnected, ensuring that students build a solid and cumulative understanding of the concepts, with detailed examples, varied exercises, and full-color illustrations. Special sections dedicated to real-world and technological problems demonstrate how trigonometry is applied in everyday situations, inspiring and motivating students to see the relevance of trigonometry beyond the classroom, across fields ranging from engineering to physics and beyond.
- An engaging introduction to the fundamentals of trigonometry and key applications
- Walks logically through topics, from basic conventions to trigonometric relations, angles and reference values, identities and functions, equations, measurement systems, laws, theorems, and coordinate systems
- Considers a range of interdisciplinary applications, from engineering to physics and beyond
- Includes detailed examples, exercises, application case studies, and full-color illustrations
