Duoduo: Here is your present. I bought it last weekend.
Qiqi: Thank you. Where did you go?
Duoduo: I went to Beijing.
Qiqi:
Duoduo: I went there with my parents.
Qiqi:
Duoduo: Yes, we did. We also took many photos there.
Qiqi: What else did you do?
Duoduo:
Qiqi: Cool!
Duoduo: Because he is hard-working(勤奋的). He became blind when he was a child, but he could play the piano very well when he was 16.
Qiqi:
Duoduo: No, he couldn't. So it was difficult for him to play the piano.
Qiqi: Oh! What a great man!

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
