The meaning of sine is 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. 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. 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 functions are cosine [cos], tangent [tan], secant [sec], cosecant [csc], and cotangent [cot].)
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 mathematics. Below is a table of values illustrating some key sine values that span the entire range of values. The sine function (simply defined as the ratio of the perpendicular to the hypotenuse of a right triangle) is a fundamental element of trigonometry with applications spanning geometry, calculus, and various scientific fields. (in a right triangle) the ratio of the side opposite a given acute angle to the hypotenuse. See examples of sine used in a sentence.
The sine function is one of the basic functions encountered in trigonometry (the others being the cosecant, cosine, cotangent, secant, and tangent)
