Trigonometric ratios are the ratios of the sides of a right triangle to the angles opposite or adjacent to them. The three most common trigonometric ratios are sine (sin), cosine (cos), and tangent (tan). They are defined as follows:

Sin(x) = Opposite side / Hypotenuse
Cos(x) = Adjacent side / Hypotenuse
Tan(x) = Opposite side / Adjacent side

Each of these ratios can be used to find the measure of an angle or the length of a side in a right triangle, given the measure of one angle and the length of one side. The reciprocal ratios, cosecant (csc), secant (sec) and cotangent (cot) are also used in trigonometry.

These ratios are useful in a variety of fields, including physics, engineering, and navigation. They are also used to model periodic phenomena, such as waves, and to graph and analyze trigonometric functions.
