cosines
Adjacent over hypotenuse
Cosines is the plural of cosine, a trigonometric function.
In a right triangle, the cosine of an angle is the ratio of the adjacent side to the hypotenuse.
More broadly, cosine describes the relationship between angles and sides in triangles, essential in mathematics, physics, and engineering: The cosines of complementary angles add up to one.
