WebThe trigonometric ratios can be defined for angles greater than 0 ∘ and less than 90 ∘ using right triangles. In particular, sin. . ( θ) is defined as the ratio of the lengths of the opposite leg and the hypotenuse, and cos. . ( θ) is defined as the ratio of the lengths of the adjacent leg and the hypotenuse.
