Hello, I’m Alice. I’m a student in Shiyan School. I like reading books. So I often go to the bookstore on Sunday. Usually, I go by subway. Sometimes I go by bike. The bookstore is far from my home. I know the traffic lights very well. They are the same in every country. Red means stop and wait. Yellow means slow down and stop. Green means you can go. We should remember the traffic rules.

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
