Ratio: A ratio is a comparison between two quantities. In trigonometry, ratios are used to express the relationship between the sides of a right triangle.

Opposite Side: The opposite side refers to the side of a right triangle that is directly across from a given angle. It is one of the three sides used in trigonometric functions like sine and tangent.

Cosine: Cosine is a trigonometric function that relates an angle in a right triangle to the ratio of the length of the adjacent side to the hypotenuse.
