Sin cos tan values are the primary functions in trigonometry. Learn the values for all the angles, along with formulas and table. Also, learn to find the values for these trigonometric ratios.
Cos 0° = sin (90° – 0°) = sin 90° for value of X = 30° cos 30° = sin (90° – 30°) = sin 60°. for value of X = 45° Cos 45° = sin (90° – 45°) = sin 45° for value of X = 60° cos 60° = sin (90° – 60°) = sin 30° for value of X...
cos是邻边比斜边，sin是对边比斜边，tan是对边比邻边。在直角三角形当中，正弦是等于对边比斜边，余弦等于邻边比斜边，正切等于对边比邻边。三角函数是初等函数之一，要以视角为变量，视角相匹配任意角终边与单位圆交点坐标或者其比率为解释变量的函数公式，还可以等额的地用与单位圆相关的各种各样线段的...
