sin per coseno In mathematics sine and cosine are trigonometric functions of an angle The sine and cosine of an acute angle are defined in the context of a right triangle for the specified angle its sine 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 and the cosine is the ratio of the length of the adjacent leg to that of the hypotenuse Fo
The six trigonometric functions can be defined as coordinate values of points on the Euclidean plane that are related to the unit circle which is the circle of radius one centered at the origin O of this coordinate system While right angled triangle definitions allow for the definition of the trigonometric functions for angles between 0 and radians 90 the unit circle definitions allow the domain of trigonometric functions to be extended to all positive and negative real numbers The three main functions in trigonometry are Sine Cosine and Tangent They are just the length of one side divided by another For a right triangle with an angle Sine Function sin
