The oldest monkey hung(悬挂) in the tree upside down, with his feet on the branch(树枝). He pulled the next monkey’s feet with his hands. All the other monkeys followed. Soon they joined each other one by one down to the moon in the well. C. One day, a little monkey was playing by the well(井). He looked into the well and shouted, “Oh, the moon fell into the well.” D.

They looked at the moon in the well and were so surprised to shout, “The moon did fall into the well.” |

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
