It’s sunny today. My friends and I are playing on the beach(沙滩). It’s very beautiful. The water is clean and blue. We are having a good time. Many birds are flying over the sea. Some are standing on the rocks(岩石). Many people are swimming. Some people are lying(躺) on the beach. Some boys are playing football. My sister is on a chair and singing. My brother John is playing with sand(沙子). What a nice day! What are you doing? I hope I can get your letter soon.
Best wishes!
Sam

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
