小男孩 | 4 | 4 | 7 | 8 | 8 | 9 | 7 | 9 |
(1)抓尺子的次数相同,总得分越高,说明反应越
(2)小女孩和小男孩相比
(3)经常玩抓尺子游戏,可以使我们的反应变

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
