Supplementary mathematics/Trigonometry

Trigonometry is one of the most important and best arithmetic calculations. Of course, trigonometry has six components to calculate. Read the definition of trigonometry well.

What is trigonometry?

Trigonometry is one of the branches of arithmetic and mathematics that examines the relationship between lengths and angles of triangles and makes a formulation for the relationship between angles and side lengths for triangles. In short, Shore said that scientific trigonometry is for Triangle is used to calculate the length and sides of a triangle. The word trigonometry comes from the Greek word (trigon, metron) which means triangle and size, respectively, and in the compound word, it means the measurement of a triangle.This concept was first given by the Greek mathematician Hipparchus. Trigonometry can only be calculated for right triangles and different triangles are not used.Trigonometry is divided into two hypothetical branches, spherical trigonometry (space) and circular trigonometry (plane).Angles in trigonometry are calculated in radians. Trigonometry, in general, is about trigonometric formulas, trigonometric ratios, and functions, right triangles, etc.

History

The history of trigonometry goes back to BC, due to the lack of sources, it is not possible to say which civilization invented trigonometry, but we know that Iranians, Arabs, Greeks, Babylonians, Germans, Latins, etc. thought about this issue.In order for humans to be able to find the sides and angles of a triangle, they came up with the idea of trigonometry. In the Babylonian, Sumerian and Greek texts, such calculations for the sides and angles can be seen in the basic trigonometric method.Of course, Iranian, Arab, English, French, German, etc. scientists took steps in the field of trigonometry and used trigonometry in other topics such as Fourier series, integral, function, analytic geometry, derivative, spatial geometry, etc., which require calculations. They have included trigonometry.
