Abstract

This chapter delves into the essentials of trigonometry, covering angle measurements in degrees, radians, and grads, and providing practical examples for conversions. It explores trigonometric functions for right triangles, including sine, cosine, and tangent, and their applications in solving real-world problems. The chapter also discusses the Law of Sines and Cosines, area calculations using Heron's formula, and important trigonometric relationships. Additionally, it introduces hyperbolic functions and demonstrates how to solve trigonometric problems using MATLAB, offering a unique blend of theory and practical application. The chapter concludes with examples of plotting trigonometric functions and calculating their periods, providing a comprehensive overview of the subject.
