In mathematics, sine and cosine are trigonometric functions of an angle.

Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: To calculate them: Divide the length of one side by another side. Example: …

sine, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, is sin A = length of side opposite angle A / length of hypotenuse. (The other five trigonometric …

Feb 18, 2025 · The sine function, commonly written as sin (θ), is the ratio of the opposite side to the hypotenuse of a right triangle. It is one of the primary trigonometric functions used in …

The sine function, along with cosine and tangent, is one of the three most common trigonometric functions. In any right triangle, the sine of an angle x is the length of the opposite side (O) …

The sine function is used to represent sound and light waves in the field of physics. In this article, we will learn the basic properties of sin x, sine graph, its domain and range, derivative, …

Sine, written as sin⁡ (θ), is one of the six fundamental trigonometric functions. There are two main ways in which trigonometric functions are typically discussed: in terms of right triangles …

The sine function is defined by determining the ratio of the length of the side opposite a reference angle (acute angle) to the length of the hypotenuse of a right triangle.

This page explains the sine, cosine, tangent ratio, gives on an overview of their range of values and provides practice problems on identifying the sides that are opposite and adjacent to a …

The classical definition of the sine function for real arguments is: "the sine of an angle in a right‐angle triangle is the ratio of the length of the opposite leg to the length of the hypotenuse."
