Trigonometry  Wikipedia
Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships between side lengths and angles of triangles.The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. In particular, 3rdcentury astronomers first noted [citation needed] that the ratio of the lengths of ...

Trigonometry developed from a need to compute angles and distances in such fields as astronomy, mapmaking, surveying, and artillery range finding. Problems involving angles and distances in one plane are covered in plane trigonometry.Applications to similar problems in more than one plane of threedimensional space are considered in spherical trigonometry.

Trigonometry. The study of angles and of the angular relationships of planar and threedimensional figures is known as trigonometry. The trigonometric functions (also called the circular functions) comprising trigonometry are the cosecant, cosine, cotangent, secant, sine, and tangent.The inverses of these functions are denoted , , , , , and .Note that the notation here means inverse function ...
