Dear Sarah,
Last Monday was a school holiday. My friends and I had a great day at the Zhongshan Park. The park is very big. We can do many things there. I flew kites with John and Zhang Peng. Liu Yun, Amy and Chen Jie sang and danced. We were all very happy.
At 12 o’clock, we had lunch. We had some fruit, some juice and hamburgers. In the afternoon, we drew some pictures of the trees and flowers in the park. On Tuesday we put the pictures on the wall in our classroom. Do you like going to the park?
Love
Wu Yifan

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
