Trigonometry

Trigonometry is a branch of mathematics that studies the relationships between the angles and sides of triangles, particularly right-angled triangles. It introduces key concepts such as sine, cosine, and tangent, which are functions that describe these relationships. Trigonometry is fundamental in various fields, including physics, engineering, and computer science, enabling the analysis of periodic phenomena, navigation, and wave motion. The subject also extends beyond triangles to include circular functions and their applications in modeling real-world scenarios. In addition, trigonometric identities and equations are crucial tools used for simplifying expressions and solving problems in advanced mathematics.
