Trigonometry is a branch of mathematics that deals with the study of triangles and
the relationships between their sides and angles. It's a fundamental field in
mathematics, extensively used in various scientific and engineering disciplines.

At its core, trigonometry explores the properties of right triangles, where one of the
angles is always 90 degrees. The three primary trigonometric functions, sine, cosine,
and tangent, are defined in relation to the angles of a right triangle. These functions
express the ratios of the lengths of the sides of a triangle.


● Sine (sin) is the ratio of the length of the side opposite an angle to the length
of the hypotenuse.
● Cosine (cos) is the ratio of the length of the adjacent side to the length of the
hypotenuse.
● Tangent (tan) is the ratio of the length of the side opposite an angle to the
length of the adjacent side.


Trigonometry extends beyond just right triangles, with the unit circle being a crucial
concept. By placing a circle with a radius of 1 unit centered at the origin of a
coordinate plane, trigonometric functions are defined based on the coordinates of
points where the terminal side of an angle intersects the unit circle.

Trigonometric identities, equations, and functions play a significant role in solving
problems related to angles and distances. They are extensively applied in fields such
as physics, engineering, astronomy, and navigation, among others.

In summary, trigonometry is a powerful mathematical tool for analyzing triangles and
periodic phenomena, with wide-ranging applications in various real-world contexts.
