滴水量/mL | 20 | 40 | 60 | 80 | 100 | … |
时间/分 | 1 | 2 | 3 | 4 | 5 | … |
(1)滴水量和时间成( )比例。
(2)这个水龙头每时滴水多少升?
(3)如果用一个底面积是10dm2,高是3dm的圆柱形水桶接的水,那么多长时间能接满?(水桶的厚度忽略不计)

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
