I’m Liu Zhaoyang. There are some festivals (节日) in China. New Year is in the first month of the year. It’s in winter. Sometimes it snows. I can make snowmen with my brother. Tree Planting Day is on March 12th. It’s in spring. I plant trees and flowers with my parents on Tree Planting Day every year. I feel very happy. Mid-Autumn Day (中秋节) is my favorite festival. It’s often in September or October. I like to eat mooncakes (月饼) on the festival. I can have many delicious fruits on Mid-Autumn Day, too.

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
