Just to add that I also found it a bit surprising that np.cos(np.pi) != -1 exactly, especially since np.mod(np.pi, np.pi/2) is correctly equal to exactly 0, so if this is done in the first quadrant and then mirrored one would expect it. But np.sin(np.pi/2) is also not...
将(1)中的x用\frac{\pi}{2} -x代,再利用诱导公式,可以得到正弦函数的和差角公式: \sin(x+y)=\cos y\sin x+\cos x\sin y(3) (3)式的y代成-y,有 \sin(x-y)=\cos y\sin x-\cos x\sin y(4) (3)/(2),(4)/(1),得到正切函数的和差角公式: \tan(x+y)=\frac{\tan x+\tan...
