There was once a shoemaker. He was poor. He had nothing but just enough leather to make one pair of shoes. That night he put the leather on the worktable and went to sleep. The next morning, the shoemaker was very surprised to see a pair of shoes. Soon after, a customer came, and bought the shoes at a very high price. Then the shoemaker had enough money to buy leather to make more shoes. He cut out the leather at night, and wanted to make shoes the next morning . When he got up, the shoes were already finished. This went on for some time. The shoemaker quickly became rich. Whenever the old man saw his neighbours or the poor people in need, he would help them. One night not long before Christmas, the shoemaker and his wife decided to stay awake to see who helped them. At midnight, they saw some naked elves start to make shoes. And when the sun rose, they quickly hid themselves. The shoemaker and his wife wanted to show their thanks. They made the elves some clothes. The elves were very happy.

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
