Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It is used to solve problems involving right triangles and is also applied in fields such as physics, engineering, and astronomy.
The basic trigonometric functions are sine, cosine, and tangent. These functions relate the angles of a triangle to the ratio of its sides. Sine is equal to the opposite side divided by the hypotenuse, cosine is equal to the adjacent side divided by the hypotenuse, and tangent is equal to the opposite side divided by the adjacent side.
Trigonometry can be used to solve real-world problems involving angles and distances. For example, it can be used to determine the height of a tree by measuring the angle of elevation from the ground to the top of the tree and using trigonometric functions to calculate the height.
The key concepts in trigonometry include angles, right triangles, trigonometric functions, and the Pythagorean theorem. Understanding these concepts is essential in solving trigonometry problems.
Trigonometry has many practical applications in various fields, including architecture, navigation, surveying, and astronomy. It is also used in industries such as construction, engineering, and aviation for calculating distances, heights, and angles.
