I went to Beijing for a travel last year with my parents. It was a happy trip. There were any places to visit. We went to see the Great Wall, the Summer Palace and the Tian'anmen Square. China has a long history. The Summer Palace is old. The Tian'anmen Square is very big. The Great Wall is famous. And it's very long. We can't walk all of it. We took some photos of the Great Wall.

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
