Sine, Cosine and Tangent Functions
Sine, cosine, and tangent functions are fundamental components of trigonometry, a branch of mathematics that deals with the relationships between the angles and sides of triangles. These functions, often denoted as sin, cos, and tan respectively, play a crucial role in various fields such as physics, engineering, and navigation. Understanding their properties and behaviors enables us to analyze and solve a wide range of problems involving angles and distances. In this introduction, we will explore the definitions, properties, and applications of these essential trigonometric functions, shedding light on their significance in mathematical discourse.
