Trigonometric ratios are the ratios between edges of a right triangle. These ratios are given by the following trigonometric functions of the known angle A, where a, b and h refer to the lengths of the sides in the accompanying figure: • Sine function (sin), defined as the ratio of the side opposite the angle to the hypotenuse.
