Hello, I'm Chen Yao. I'm a student. I always get up at seven. Then I brush my teeth and wash my face. I have breakfast at half past seven. After breakfast, it's time to go to school.
I live in a big city. Usually, there are many cars and they make the air dirty. But today many people don't drive their cars. Because today is World Car Free Day. It's time to do something for our earth. I think I should go to school on foot today.

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
