Frank: Yes.
Alice: I heard a baby panda was born in the zoo. Let’s go and have a look.
Frank: Oh, I have been there twice. I think you’d better learn something about pandas before you go to the zoo.
Alice: I know a little.
Frank: That’s true. They are endangered now.
Alice: Why? Is it because they don’t have babies very often?
Frank:
Alice: What a pity!

Alice: I will take some photos of the pandas first when I visit the zoo.
Frank:
Alice: Thank you.

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
