Hello, Tom. We're Laura and Amy. We want to be your pen friends. We live in Beijing. There are many places worth seeing in Beijing. Amy has got a Chinese kite and we often fly it in the park. We like Chinese food. We've got some chopsticks, but they were difficult for us to use. Now we can use chopsticks very well. We've got some stamps from China, too. Have you got a book about China? We can send you one.

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
