Sine and cosine - Wikipedia
In mathematics, sine and cosine are trigonometric functions of an angle.
Sine, Cosine and Tangent - Math is Fun
Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle: Opposite is always opposite the angle. And Adjacent is always next to the angle.
Cosine | Definition, Formulas, & Facts | Britannica
The cosine is a fundamental trigonometric function such that the cosine of an angle of a right triangle is the ratio of its adjacent side to the hypotenuse.

Cosine - Math.net
Cosine, written as cos (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 and in terms of the unit circle.
Cosine Function (Cos) - GeeksforGeeks
The cosine function (cos) is one of the fundamental trigonometric functions used in mathematics, primarily in the study of angles and triangles. In simple terms, the cosine of an angle in a right-angled triangle is the ratio of the length of the adjacent side to the length of the hypotenuse.
Sine and Cosine | Algebrica
Sine and cosine, denoted as sin (θ) and cos (θ), are fundamental trigonometric functions that associate each angle, defined from the unit circle, with a value between -1 and +1.
Cosine - math word definition - Math Open Reference
The cosine function, along with sine and tangent, is one of the three most common trigonometric functions. In any right triangle, the cosine of an angle is the length of the adjacent side (A) divided by the length of the hypotenuse (H). In a formula, it is written simply as 'cos'.
Cosine - Graph, Meaning, Period, Examples | Cosine Function
The cosine can be defined as the ratio of the length of the base to the length of the hypotenuse in a right-angled triangle. It gives the value of the cosine function for angle x, denoted by cos x.
MFG The Sine and Cosine Functions - University of Nebraska–Lincoln
The special values of sine and cosine in the first quadrant are very useful to know, since knowing them allows you to quickly evaluate the sine and cosine of common angles without needing to look at a reference sheet or use your calculator.
