When you are in Britain, you can often see people go out with umbrellas or raincoats on a sunny day. Why? Because the weather in Britain often changes quickly. The same weather doesn’t stay for long. People can experience (经历) four seasons in one day. In the morning, the weather is warm like in spring. After an hour, black hours come and then it rains. The weather gets cold. In the late afternoon, it is sunny. The sun begins to shine, and it is summer at this time of a day. The weather is always changing. How interesting it is!

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
