Cold air. Snow. Shorter days. We are in winter now.
Winter is the coldest season of the year. It comes between autumn and spring. For people who live in the northern part of the earth, it is really cold. In China, the winter months are usually November, December and January. It often snows, sometimes very hard. The land is covered with snow. The whole world becomes white. Winter isn’t always white. It can also be bright. There are a lot of winter activities. You can go outside and enjoy yourself. It’s a good idea to make a snowman with your friends. And you can go skating and skiing. If you really have to stay indoors, you can watch movies and spend time reading. You’ll also find it a lot of fun.
However, in the southern part of the earth, it is opposite! It is summer in November, December and January. The weather is very hot. People enjoy activities like swimming and surfing. Imagine when we are playing with snow, Australian kids are enjoying ice cream! And it also feels strange to have Christmas in summer!

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
