The meaning of COSINE is a trigonometric function that for an acute angle is the ratio between the leg adjacent to the angle when it is considered part of a right triangle and the hypotenuse.
1.In a right triangle, the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse. 2.The abscissa at the endpoint of an arc of a unit circle centered at the origin of a Cartesian coordinate system, the arc being of lengthxand measured counterclockwis...

1. The cosine of an angle in a right-angled triangle is the ratio of the length of the adjacent side to the length of the hypotenuse. 2. In trigonometry, the cosine function is used to calculate the length of a side in a right-angled triangle when the length of another side and an...
Recently, Cosine similarity has become a popular alternative choice to the standard Euclidean metric, in particular in the context of textual data and neural network embeddings. Unfortunately, Cosine similarity is not metric and does not satisfy the standard triangle inequality. Instead, many search ...

Cosine rule, in trigonometry, is used to find the sides and angles of a triangle. Cosine rule is also called law of cosine. This law says c^2 = a^2 + b^2 − 2ab cos(C). Learn to prove the rule with examples at BYJU’S.
For example, let’s calculate the cosine of angle α in a triangle with the length of the adjacent side equal to 6 and the hypotenuse equal to 8. cos(α) =6/8 cos(α) =3/4 Cosine Graph If you graph the cosine function for every possible angle, it forms a repeating up/down curve...
trigonometry [Gr.,=measurement of triangles], a specialized area of geometry concerned with the properties of and relations among the parts of a triangle. Spherical trigonometry is concerned with the study of triangles on the surface of a sphere rather than in the plane; it is of considerable ...
