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."

what is the cosine of 3.14 ?

Cosine of 1 degree is about 0.999848. Cosine of 1 radian is about 0.540302.

Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.

Cosine is 0.766
