Winter is the last season in a year. I like it best. In China, the weather is not the same in winter. In Harbin, it's very cold. It often snows. People can play with snow and they must put on the coat. But in Sanya, it's not cold. It's very warm. People there can go swimming in the sea. The weather is so different in winter between Harbin and Sanya, is it funny?

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
