cosine: In a right triangle, the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse.
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 ...
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 ...

In a right triangle, the cosine of an angle is found by dividing the length of the adjacent side by the hypothenuse. If the angle is not acute, use the unit circle and similarity of triangles. What is the definition of the cosine of an angle?
