My name is Li Hua. I take care of a panda. His name is Yuanyuan. He is three years old. Every morning he gets up at six thirty. I give him breakfast at seven thirty. He likes to have some bamboo shoots. After breakfast, Yuanyuan will play with balls with his friends. We have many visitors every day. All the children and their parents like Yuanyuan very much. Yuanyuan has lunch at twelve thirty. His lunch is not always the same. After lunch, he goes back to his room to have a rest. He comes out to play again in the afternoon. There are many toys for pandas. He has supper at six. He goes to bed at about eight. That is his day.

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
