AI overview
Cosine is a fundamental mathematical function that describes the relationship between the angles and sides of a right triangle, calculated as the ratio of the adjacent side to the hypotenuse. It's widely used in fields ranging from physics and engineering to computer graphics and signal processing because it helps solve problems involving waves, rotations, and periodic patterns.
