How are you? I'm so happy. Because I have a new friend. Her name is Li Shan. She comes from China. She is tall and thin. Her eyes are big. And her hair is very long. She is beautiful in orange. We often play games after class. She can speak a little English. We are good friends. How about you? Do you have any new friends? Tell me something about them.
Yours,
Amy

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
