| Dear grandma, Thank you very much for the bag you sent me for my birthday. It was really nice of you. I'm going on holiday next month, so I'm planning to take it while I'm away! I hope you're well. Love， Cindy |
| Dear Mr. Green, I am writing to say thank you for letting us stay in your house in Australia last month. We were very happy with everything and we thought the house was beautiful. We had a lovey holiday in Sydeny. We really enjoyed exploring （探索） the town and the local area. We will use the "Love A Flat" website again to find a house to live in when we plan our next holiday. Thank you again! Yours, Costa |

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
