①三黑就是这样地翻着土地。/从东到西,从南到北,/每一寸土都给翻起,/每一块土疙瘩都给细细打碎。
②地翻好,又耙了几遍,/耙得又平又顺溜,/看起来/好像妇女们刚梳的头。
1.种地之前三黑都做了什么?用横线画出。2.从中可以看出三黑对土地的

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
