Yesterday Lucy was very sad, because her cat was in the tree. She called it again and again, but it couldn’t get down. Peter was a good boy. He came there and asked Lucy, “What’s wrong with you?” Lucy said, “Mimi can’t get down from the tree. It’s afraid. Look, it’s there.” “Don’t worry, I can help you.” said Peter. Then he climbed up the tree. Mimi saw him and jumped down from the tree and ran away. Lucy was happy and ran after her cat. What about Peter? He was sad! Because he didn't know how to get down!

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
