sin120°的值是√3/2。在单位圆中，正弦函数sinθ表示的是从原点出发，沿着x轴正方向逆时针旋转θ角度后，与单位圆交点的y坐标值。当θ等于120°时，我们可以想象在单位圆上找到这个角度对应的点，并找到该点的y坐标值。根据三角函数表或单位圆的性质，我们知道在角度为...
As our angle of interest is Sin 90. So accordingly, the Sin function of an angle or Sin 90 degrees will be equal to the ratio of the length of the opposite side to the length of the hypotenuse side. Sin 90 Formula opposite sidehypotenuse side Method to Derive Sin 90 deg Value Let us...
