某市各大工厂捐赠口罩统计图
(1)根据统计表和统计图信息,可知统计图中每格代表( )个。
(2)从图中可以看出( )厂捐赠的口罩最多,甲厂捐赠的口罩比丙厂少( )个。
(3)根据统计图,请提出一个数学问题并解答?

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
