Today I went to see my penfriend in Hongye Hotel. We had a talk for a long time. How happy we were! He's from America. His name is Paul. He came to visit China two days ago. He's interested in reading, playing basketball and making penfriends. He also wants to learn Chinese. He hopes I can visit America one day.

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
