1.根据图中各点所对应的数据完成上表.
2.图象中每个点都对应着( )和( ),而且对应数据的( )相等,也就是( )不变,所以图象显示两个量成( )关系.
3.反比例关系的图象是( ),根据图象估计,要求8小时行完全程,每小时要行( )千米.

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
