| Hi Li Hua, How’s it going? Thanks for inviting (邀请）me to your home. Can you tell me something about your family? And what sports do your family like? I really want to play sports with you! And I'm also very excited to visit your school next term! What activities do you have in your school? Write to me soon. |

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
