The little squirrel(松鼠)was in the tree. The fox came and said to her, “Your father can jump with closed eyes. Can you do that?” The squirrel answered, “I can do that, too.” She closed her eyes and jumped. She fell down from the tree. The fox caught her and wanted to eat her at once. “Wait a minute. I will ask you a question. Your father always washes his hands before he eats something, can you?” said the squirrel quickly. The fox answered, “Of course.” When he loosened(松开)his hands, the little squirrel ran up to the tree.

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
