There is a cat in the forest. The cat’s name is Betty. Betty is three years old. One day she went to visit her grandmother. But she was lost. She met an old bird. She said, “excuse me, can you help me? I’m lost.” The old bird flew away. The dog appeared and said, “I can help you.” The dog then said, “go straight and turn left at the tree. Your grandmother’s house is there.” Betty said, “Thank you.” The dog said, “You’re welcome!” Betty happily ran to her grandmother’s house.

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
