Description: Get the cosine of an angle
Cosine (cos) is a fundamental trigonometric function that, in a right-angled triangle, defines the ratio of the Adjacent side (next to the angle) to the Hypotenuse (the longest side), calculated as cos(θ) = Adjacent / Hypotenuse, used widely in math, physics, and engineering for calculating distances, waves, and forces. It's also defined on the unit circle as the x-coordinate of a point and can be extended to all angles, with values always between -1 and 1.
