## Definitions

### from The American Heritage® Dictionary of the English Language, 5th Edition.

• noun 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.

### from The Century Dictionary.

• noun The mathematical doctrine of the calculation of the angles, sides, and areas of triangles, plane and spherical, together with that of other quantities intimately related to those. Trigonometry embraces also goniometry, or the elementary theory of singly periodic functions.

• noun A treatise in this science.
• noun that branch of trigonometry which treats of the relations and properties of the trigonometrical functions.
• noun those branches of trigonometry in which its principles are applied to plane triangles and spherical triangles respectively.

• noun mathematics 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.
