(1)用计算器计算下面各题
1÷9= 2÷9= 3÷9= 4÷9=
5÷9= 6÷9= 7÷9= 8÷9=
你发现了什么规律?
(2)先用计算器计算前三题,再用发现的规律直接写出后面各题的得数
10÷9= 11÷9= 12÷9= 13÷9=
14÷9= 15÷9= 16÷9= 17÷9=

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
