Hello, boys and girls. I’m David. I’m from the UK. Christmas is my favourite festival. At Christmas, we sing songs. There is a big Christmas tree in my house. We give presents. We says, “Merry Christmas!” And we can eat a lot of food. What do you do at the Spring Festival in China? I think it must be interesting. Can you tell me?

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
