How nice to get your e-mail! I’m having a good time with my family in China. The day before yesterday, we flew to Chengdu. It’s a city in the west of China. It is famous for its hot, spicy(辣的) food. The food is delicious and the people are friendly. Yesterday, we flew to Kunming. It’s a city in the southwest of China. It is famous for its flowers. The weather there was warn. We watched flower shows there. Today, we took a train to Hangzhou. It’s a city in the southeast of China. It is near Shanghai. There are many beautiful gardens here. This city is famous for silk (丝绸). We bought some beautiful silk clothes here. Tomorrow morning we will go to Xi’an. It’s an old city. I can know more about China.
Yours truly,
Linda

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
