| Dear Janet, I am now in Shenzhen. Shenzhen was a small town forty years ago. But now it’s a big and modern city. It’s one of the most important cities in China. There are many tall buildings in Shenzhen. I love living here! I have two new good friends here. Sam is from Beijing and Peter is from Sichuan. It’s a lot of fun to go out to have meals with my friends. Before, Sam loved salty food. Peter loved hot food and I loved sweet food. But now, We enjoy different tastes of food. The traffic in the city is sometimes terrible! I go to school by bus every day. It takes me between 10 minutes and 50 minutes to get to school. With no traffic, it’s 10 minutes. With heavy traffic, it is 50 minutes! I wish I can meet you in Shenzhen. Yours, Jacky |

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
