Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It is a fundamental concept in geometry and is used in various fields such as physics, engineering, and astronomy.
The study of trigonometry involves understanding trigonometric functions such as sine, cosine, and tangent, which relate the angles of a triangle to the lengths of its sides. These functions are essential for solving problems involving triangles and can be used to calculate distances, heights, and angles.
Trigonometry is also used to analyze periodic phenomena, such as sound waves and electromagnetic waves, as well as to model complex systems in mathematics and physics. It provides a powerful tool for understanding the world around us and is essential for many scientific and technical disciplines.
