Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It involves the study of the properties of trigonometric functions, which are mathematical functions that relate the angles of a right triangle to the ratios of the lengths of its sides. The three primary trigonometric functions are sine, cosine, and tangent, and they are used to calculate angles and distances in a variety of fields, including engineering, physics, and astronomy. Trigonometry also includes the study of inverse trigonometric functions, which allow one to determine the angle that corresponds to a given trigonometric ratio.
