Bookmark or Share- Sine, Cosine, Tangent - Math is FunSine, 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. Example: What is the sine of 35°?
- Laws of sines and cosines review (article) | Khan AcademyWant to learn more about the law of cosines? Check out this video. Practice set 1: Solving triangles using the law of sines. This law is useful for finding a missing angle when given an angle and two sides, or for finding a missing side when given two angles and one side. Example 1: Finding a missing side. Let's find A C in the following triangle:
- Sine Definition & Meaning - Merriam-Webster1. : the trigonometric function that for an acute angle is the ratio between the leg opposite the angle when it is considered part of a right triangle and the hypotenuse. 2. : a trigonometric function sin θ that for all real numbers θ is exactly equal to the sine of an angle of measure θ in radians and that is given by the sum of the ...
- Sine -- from Wolfram MathWorldSine. Download Wolfram Notebook. The 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.
- Sine - Math.netSine. Sine, 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 right-angled triangle definition of trigonometric functions is most often how they are ...
