Trigonometry 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.

Answer 2

HELLO DEAR FRIEND

trigonometry ➡ the type of the mathematics in which deals with the relationship between the sides and angles of a right angle triangle .

It has six ratios.

1. sin theta = perpendicular / height

2. cos theta = base / height

3. tan theta = perpendicular / base

4. cosec theta = height / perpendicular

5. sec theta = height / base

6. cot theta = perpendicular / base.

NOTE ➡ The first trigonometric table was apparently compiled by

$\large \underline{Hipparchus \: \: of \: \: Nicaea.}$
