There is a rich old businessman in a small town. He has a lot of money. One day, he meets three men, a factory worker, a coach and a fisherman. He gives them three seeds(种子) and says, “Bring me the flowers in three months. The man with the most beautiful flower can have my money!”
After three months, the factory worker brings a big red flower, the coach brings a small purple flower. But the poor fisherman brings nothing. He is very sad.
“I don’t know why!” he says. “I watered it every day.”
“You are honest!” the businessman says. “The seeds are bad and will never sprout(发芽). The money is yours!”
The fisherman is very happy, and the other two men feel ashamed and sad.

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
