Spring is warm and sunny. The trees are green and flowers are beautiful. We can plant trees and run oil the grass. Summer is my favourite season. It is very hot, and sometimes it rains. I like swimming in the swimming pool. And I can wear my beautiful dresses. I can eat ice creams. Fall is a beautiful season. The weather is very cool. We can eat a lot of fruits. And the leaves are colourful. Winter is very cold. But in Hainan it does not snow. We can not play with the snow. I like the four seasons very much.

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
