Share on X Share on Pinterest Cite How to Find the Cosine of an Angle 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. ...
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...
FAQs on Cosine Function What is Cosine in Trigonometry? The cosine of an angle is a trigonometric function. The ratio of the lengths of the side adjacent to the angle and the hypotenuse of a right-angled triangle is called the cosine function which varies as the angle varies. It is ...

As we have learned on this page, we have multiple cosine formulas and we can choose one of them to prove a trigonometric identity (or) find the value of the cosine function with the available information. We can use the cosine formulas to find the missing angles or sides in a triangle....
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.
