1.“这条小鱼在乎!”小男孩一边回答,一边捡起一条小鱼扔进大海,“这条在乎,这条也在乎!还有这一条、这一条、这一条……”
1.这段话表现了小男孩什么样的品质?想好后写一写。
2.用不了多久,浅水洼里的水就会被沙粒吸干,被太阳晒干。这句话说明了什么?作者为什么要这样写?

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
