Trigonometric ratios are ratios of the lengths of the sides of right triangles. They are used to find the sine, cosine, and tangent of an angle.
The trigonometric ratios of some specific angles are:
Sine: The ratio of the length of the opposite side to the length of the hypotenuse is equal to the sine of the angle.
Cosine: The ratio of the length of the adjacent side to the length of the hypotenuse is equal to the cosine of the angle.
Tangent: The ratio of the length of the opposite side to the length of the adjacent side is equal to the tangent of the angle.
These ratios can be used to find the values of trigonometric functions for any angle. For example, if we know the sine of an angle is 0.5, we can find the cosine of that angle by using the following formula:
Similarly, we can find the tangent of an angle by using the following formula:
Trigonometric ratios are used in various applications, including surveying, trigonometry, and physics. They can be used to find the distances of objects from a known location, the heights of buildings, and the speeds of projectiles
