I am going to tell you about my life in China. I study in Zhuhai. I live near the school. So I can go to school on foot. But I often go by bike. Because that’s fun. My mother is an English teacher. My father works in a science museum. We often play football at 5:30 pm. But sometimes we go shopping. I have a new friend WuYifan. He is in Harbin now. I am going to fly there. What are you going to do this winter holiday?
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
