How are these functions calculated?
Sine, cosine, and tangent are all calculated using ratios of the sides of a right triangle. Sine is the ratio of the opposite side divided by the hypotenuse, cosine is the ratio of the adjacent side divided by the hypotenuse, and tangent is the ratio of the opposite side divided by the adjacent side.
