Now I am in Beijing. I want to go to the Great Wall, the Palace Museum and Wangfujing Street. The Great Wall is very old and very long. The Great Wall is far from our hotel. We need to take a bus. The Palace Museum is about six hundred years old. There are old chairs and tables in it. We can take pictures in it. I will buy some gifts for my family on Wangfujing Street. I’ll be busy but happy.

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
