What is the sine function?

Back

The sine function (sin) is a trigonometric function that represents the ratio of the length of the opposite side to the length of the hypotenuse in a right triangle.

What is the cosine function?

Back

The cosine function (cos) is a trigonometric function that represents the ratio of the length of the adjacent side to the length of the hypotenuse in a right triangle.

What is the tangent function?

Back

The tangent function (tan) is a trigonometric function that represents the ratio of the length of the opposite side to the length of the adjacent side in a right triangle.

How do you find the length of a side in a right triangle using trigonometric ratios?

Back

To find a side length, use the appropriate trigonometric ratio: sin, cos, or tan, depending on the known angles and sides. For example, if you know an angle and the hypotenuse, use sine or cosine.
