There are lots of beautiful cities to go in China. If you go to Guilin, you can see many mountains and lakes. You can eat different kinds of fruits. They are very cheap. If you visit Hong kong, you can go shopping all the day. You can buy things from all over the world. If you go to Beijing, you can know more about our culture. I’m going to visit Yan’an next week. Because it’s an important place for Chinese people. I think we should know more about our history.

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
