Sine, Cosine and Tangent - Math is Fun
WEBSine, Cosine and Tangent. Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same no matter how big or small the triangle is. To calculate them: Divide the length of one side by another side
Sine and cosine - Wikipedia
WEBThe other trigonometric functions of the angle can be defined similarly; for example, the tangent is the ratio between the opposite and adjacent sides or equivalently the ratio between the sine and cosine functions. The reciprocal of sine is cosecant, which gives the ratio of the hypotenuse length to the length of the opposite side. Similarly, the reciprocal of cosine is secant, which gives ...
Trigonometric functions - Math.net
WEBThere are six trigonometric functions: sine, cosine, tangent and their reciprocals cosecant, secant, and cotangent, respectively. Sine, cosine, and tangent are the most widely used trigonometric functions.
Introduction to Trigonometry - Math is Fun
WEBSine, Cosine and Tangent. The main functions in trigonometry are Sine, Cosine and Tangent. They are simply one side of a right-angled triangle divided by another. For any angle " θ ": (Sine, Cosine and Tangent are often abbreviated to sin, cos and tan.) Example: What is the sine of 35°? Using this triangle (lengths are only to one decimal place):
Sin Cos Tan - Values, Formulas, Table, Examples - Cuemath
WEBIn trigonometry, sin, cos, and tan are the basic trigonometric ratios used to study the relationship between the angles and sides of a triangle (especially of a right-angled triangle). Understand the sin, cos, tan values using examples.
Sine - Math.net
WEBSine, written as sin (θ), is one of the six fundamental trigonometric functions. Sine definitions. There are two main ways in which trigonometric functions are typically discussed: in terms of right triangles and in terms of the unit circle.
The sine function - math word definition - Math Open Reference
WEBThe 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) divided by the length of the hypotenuse (H). In a formula, it is written as 'sin' without the 'e':

The Law of Sines - Math is Fun
WEBThe Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C. It works for any triangle: a, b and c are sides. A, B and C are angles.
Sine -- from Wolfram MathWorld
WEBThe sine function is one of the basic functions encountered in trigonometry (the others being the cosecant, cosine, cotangent, secant, and tangent). Let be an angle measured counterclockwise from the x -axis along an arc of the unit circle.
