Sine and cosine are two of the most fundamental functions in mathematics, especially in trigonometry. They describe the relationship between the angles and sides of right triangles, but their importance extends far beyond geometry. The sine function gives the ratio of the length of the side opposite an angle to the hypotenuse, while the cosine function gives the ratio of the adjacent side to the hypotenuse. On the unit circle, sine corresponds to the y-coordinate of a point determined by an angl

The sine function is one of the most important ideas in trigonometry. It comes from studying right triangles, where sine is the ratio of the side opposite an angle to the hypotenuse. More broadly, sine describes patterns of oscillation, rotation, and wave motion. Its graph is a smooth, repeating curve that goes up and down between –1 and 1, repeating every 360 degrees. Because of this, sine shows up in physics to model things like sound waves, vibrations, and circular motion. The cosine function
