How are you? We are going to see you in three weeks. Dad's going to put another bed in my room. Mum bought new T-shirts for you. Dad read a book about Chinese history. He is going to ask you some questions. And we borrowed a bike for you. Don't forget to bring some CDs of Chinese songs. We can listen to them in the evening. See you soon!

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
