Trigonometry
The basic functions of trigonometry are: sine cosine tangent secant cosecant cotangent
In trigonometry, when we look at right triangles, the cosine is the ratio of the length of the adjacent side to the length of the hypotenuse.
The same thing that cosine means in trigonometry, a calculator just allows you to calculate such functions quickly.
Trigonometry is specificly the study of a right triangle. For example, what is the cosine? Geometry is the study on shapes.
sine, cosine, tangent, cosecant, secant, cotangent.

The basic circular functions are sine, cosine and tangent. Then there are their reciprocals and inverses.
Cot in trigonometry is the cotangent, which is cosine over sine, or x over y.
As far as I know, there is no such word as "cosion." Are you asking about the mathematical term "cosine"? If so, it comes from trigonometry. In a right triangle, the cosine is the ratio of the length of the adjacent side to the length of the hypotenuse. The abbreviation for cosine is "cos."
cosecant = 1/sine secant = 1/cosine cotangent = 1/tangent
