Trigonometry - trigonometry - modern trigonometry: in the 16th century trigonometry began to change its character from a purely geometric discipline to an algebraic-analytic subject. Two developments spurred this transformation: the rise of symbolic algebra, pioneered by the french mathematician françois viète (1540–1603), and the invention of analytic geometry by two other frenchmen.

Trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). These six trigonometric functions in relation to a right triangle are displayed in the figure.
Trigonometry is one of the important branches in the history of mathematics and this concept is given by a greek mathematician hipparchus. Here, we will study the relationship between the sides and angles of a right-angled triangle. The basics of trigonometry define three primary functions which are sine, cosine and tangent.
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.
