樱桃的质量/kg | 0 | 5 | 10 | 25 | …… |
(2)樱桃的质量与箱数成正比例关系吗?为什么?
(3)把上表中箱数和樱桃的质量对应的点描在方格纸上,再按顺序连接起来。
(4)按这样装箱,45kg樱桃可以装( )箱,12个箱子最多可以装( )kg樱桃。

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
