How are you? My brother and I are having our winter holiday. Yesterday we went to the museum. We got there by bus. And then we climbed the mountain. At noon, we walked to the restaurant to have lunch. The food was delicious. It was cheap, too. We also went shopping in the afternoon. I bought clothes. When I went to bed at 22:00, I was very tired, but I was happy. We are planning (计划) to learn skating and do many other things during the holiday. We are sure we’ll have a very good time. How about your winter holiday? Please write to me soon.
Yours,
Sarah

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
