How are you?
This holiday is wonderful. The island (岛) is beautiful and the weather is hot and sunny every day. I arrived on Saturday morning and went to the beach. I took along swim and then sunbathed (日光浴) all afternoon. After that I sat under my umbrella and listened to the CD you bought me for my birthday -thanks again! On Sunday I met some boys from Japan (日本) and we played beach volleyball (沙滩排球) with some of the local (当地的) people. They were all very friendly.
Yesterday I went shopping and I bought you a nice present. I hope you like it. See you when I get home.
Love,
Helen

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
