In a right triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side.

In any right triangle, the tangent of an angle is the length of the opposite side O divided by the length of the adjacent side A. In a formula, it is written simply as ' tan '. Asked by: Regino Turov science space and astronomy What is sine cosine and tangent? Last Updated: 13th January, The cosine often abbreviated " cos " is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse.

And the tangent often abbreviated " tan " is the ratio of the length of the side opposite the angle to the length of the side adjacent. Adao Mittendorf Professional. What is the purpose of sine? In mathematics, the sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle the hypotenuse.

An Nyhues Professional. How is sin calculated? Sine sin function - Trigonometry. In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse. In any right triangle, the sine of an angle x is the length of the opposite side O divided by the length of the hypotenuse H.

Isaia Gunther Explainer. What is trigonometry formula? The six trigonometric functions are sine, cosine, secant, co-secant, tangent and co-tangent. The Sine , Cosine and Tangent functions express the ratios of sides of a right triangle. Remember: When we use the words 'opposite' and 'adjacent,' we always have to have a specific angle in mind.

The sine of an angle has a range of values from -1 to 1 inclusive. Below is a table of values illustrating some key sine values that span the entire range of values. The cosine of an angle has a range of values from -1 to 1 inclusive.

Below is a table of values illustrating some key cosine values that span the entire range of values. In the triangles below, identify the hypotenuse and the sides that are opposite and adjacent to the shaded angle. Sine , Cosine and Tangent often shortened to sin , cos and tan are each a ratio of sides of a right angled triangle:.

Divide the length of one side by another side. Good calculators have sin, cos and tan on them, to make it easy for you. Just put in the angle and press the button.
