Australia is one of the greatest countries in the world. It is smaller than China. It is in the south of the Earth. So when it is hot in summer in our country, it is cold winter in Australia. Australia is big, but the population is small. The population of Australia is almost the same as that of Shanghai, a city in China. Australia is famous for its sheep and kangaroos. After a short drive from any town, you will find yourself in the middle of white sheep. Sheep are everywhere. Did you see a kangaroo before? It has a “bag” in its body. The mother kangaroo keeps its baby kangaroo in the “bag”. It is very interesting, isn’t it?

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
