In a right triangle, the trigonometric functions are: sine θ =opposite/hypothenusecosine θ =adjacent/hypothenusetangent θ =opposite/adjacent trig·o·no·met·ric function (trĭg′ə-nə-mĕt′rĭk) A function of an angle, as the sine, cosine, or tangent, whose value is express...
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...

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.
Triangle distance is considered as the cosine of a triangle between two vectors and its value range between 0 and 2 [13]. The Bray–Curtis similarity measure [14] which is sensitive to outlying values is a city-block metric. The Hamming distance [15, 16] is the number of positions at ...

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.
In aright triangle, the cosine of angle α, or cos(α), is the ratio between the adjacent side of an angle and thehypotenuse. Cosine is one of the three primarytrigonometric functionsand is abbreviatedcos. You might be curious how to find the cosine of an angle. Use the formula below ...
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 ...
Similarity search is a fundamental problem for many data analysis techniques. Many efficient search techniques rely on the triangle inequality of metrics, which allows pruning parts of the search space based on transitive bounds on distances. Recently, Cosine similarity has become a popular alternative...
