I had a good dream last night. I was a taikonaut. Peter was in my dream. He was a taikonaut too. We were in a spaceship. We saw many stars in space. We went to the Mars (火星). It was very cold there. There was no water or air. And there were no trees. But there were Martians (火星人). The Martians were very friendly. We became friends and played games. We had a lovely time!

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
