时间/时 | 1 | 2 | 3 | 4 | 5 | … |
路程/千米 | 110 | 220 | 330 | 440 | 550 | … |
(1)根据表中数据,在下图中描出时间和路程所对应的点,再把它们按顺序连起来.
(2)(速度)是一定的量,时间和路程成( )比例.
(3)根据图象判断5.5小时行多少千米?

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
