sin180度等于0。详细解释如下:三角函数中的正弦函数,表示的是角度的正弦值。在直角坐标系中,sinθ代表的是角度θ的正弦值,也就是角θ的对边与斜边的比值。由于正弦函数的周期是360度,所以在每个周期内都有对应的正弦值。而sin180度,正好是处于正弦函数的下半周期,与sin0度相对...
sin180度等于0。关于这一知识点的详细解释如下:在单位圆中,正弦函数sinθ表示的是以原点为起点,沿着x轴正方向旋转θ角度后,射线与单位圆交点的y坐标值。当θ为180度时,这个射线将会与单位圆的最下方交汇。我们知道圆是最完美的对称图形,所以在这种情况下,交点的x坐标为原点正下...
in radians. value of sine 180 degree (π) is 0 note: sin 180° = sin 0° = 0 sin 180 – theta one interesting fact related to sin 180 degrees is sin 180 minus theta is equal to sin theta, where theta is any angle. sin (180° – theta) = sin theta sin (180° –θ) = ...
