It will be the first time that I have to look after myself. So I’m really worried about it. And I’m also afraid that I may be lonely and bored. What should I do? Can you give me some advice? Write to me soon! Best wishes to you! Yours, Lingling |

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
