cosine 英 [ˈkəʊsaɪn] 美 [ˈkoʊsaɪn]n. 余弦 牛津词典 noun 余弦the ratio of the length of the side next to an acute angle in a right-angled triangle to the length of the longest side (= the hypotenuse )
The meaning of COSINE is a trigonometric function that for an acute angle is the ratio between the leg adjacent to the angle when it is considered part of a right triangle and the hypotenuse.
You can find approximate cosine values without acalculatorby using the cosine ratio. Cosine A is equal to the length of the leg adjacent to angle A divided by the length of the hypotenuse. How do you convert cosine to an angle? To convert a cosine value to an angle, you need to find...
Thearccosineof x is defined as the inverse cosine function of x when -1≤x≤1. When the cosine of y is equal to x: cosy=x Then the arccosine of x is equal to the inverse cosine function of x, which is equal to y: arccosx= cos-1x=y ...
cosine, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, is cos A = length of side adjacent to angle A/length of hypotenuse.(The other five trigonometric functions are sine [sin], tangent [tan], secant [sec], cosecant [csc], and cotangent [co...
