I had a fantastic holiday in Dalian. It was hot and the sea was blue and lovely. I traveled by plane from London to Dalian. I really enjoyed the flight. It was thirteen hours long, but I didn’t sleep at all because I was so happy. I listened to music, saw a film and talked to the girl next to me. I stayed with my cousin in Dalian. On my last night there I went to bed at 11 o’clock!

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
