Random House Webster's College Dictionary
trig•o•nom•e•tryˌtrɪg əˈnɒm ɪ tri(n.)
the branch of mathematics that deals with the relations between the sides and angles of plane or spherical triangles, and the calculations based on them.
Origin of trigonometry:
1605–15; < NL trigōnometria; see trigon , -o -, -metry
the mathematics of triangles and trigonometric functions
The branch of mathematics that deals with the relationships between the sides and the angles of triangles and the calculations based on them, particularly the trigonometric functions.
Origin: From trigonometria, from τρίγωνον + -metria.
that branch of mathematics which treats of the relations of the sides and angles of triangles, which the methods of deducing from certain given parts other required parts, and also of the general relations which exist between the trigonometrical functions of arcs or angles
a treatise in this science
Trigonometry is a branch of mathematics that studies triangles and the relationships between the lengths of their sides and the angles between those sides. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves. The field evolved during the third century BC as a branch of geometry used extensively for astronomical studies. It is also the foundation of the practical art of surveying. Trigonometry basics are often taught in school either as a separate course or as part of a precalculus course. The trigonometric functions are pervasive in parts of pure mathematics and applied mathematics such as Fourier analysis and the wave equation, which are in turn essential to many branches of science and technology. Spherical trigonometry studies triangles on spheres, surfaces of constant positive curvature, in elliptic geometry. It is fundamental to astronomy and navigation. Trigonometry on surfaces of negative curvature is part of hyperbolic geometry.
