One day an old man is selling a big camel(骆驼). A boy comes to the camel and begins to look at it carefully. Then the old man says, “Don't say anything about the camel before I sell it. Then I will give you ten yuan.” “All right!” says the boy happily. After the old man sells the camel, he gives the boy ten yuan and says, "Now, can you tell me how you can find out the bad ear of the camel?” “I don't know which ear is bad,” says the boy. “Then why do you look at the camel so carefully?” asks the old man. “Because I never saw a camel before,” the boy answers.

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
