Dear Oliver,
How are you? I’m fine in China. I’m going to tell you something about my life here. I study in Shanghai. I live near the school. So I can go to school on foot. But I often come by bike. I think it’s fun and that’s good exercise, too. My father works in a library here. I often read books in the library on Saturday afternoon. I have a new friend here. His name is Li Lei. He is in Beijing now. I’m going to visit him next weekend. Beijing is a big city. There are many interesting places there. We are going to visit the Great Wall and the Palace Museum. They are old and great. What are you going to do next weekend?
Yours,
Jack

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
