| Hi Li Ping, How is everything going with you? Next week my cousin Mike is staying with me. We’re having a party next Saturday. Please come! We’ll have lots of drinks. But if you remember, can you bring some Chinese food? The party will be starting at 6 p.m. What time do you think you’ll be coming? I’ll probably need one or two people to help me tidy up after the party. Do you think you’ll be able to stay and help? Anyway, hope you can make it. Please write back to tell me if you can come or not. All the best. Matt |

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
