| To: LiPing@mail.com Subject: Exchange Visit! Hi there, Li Ping! My name’s Jack and I’m going to be at your school for the exchange visit next month. I’m really excited about it! Well, why am I writing right now? for one thing, I really want to know something about the interesting activities at your school, so could you introduce one of them? Also, I am interested in Chinese culture. So what do you suggest I do after school? Take care and hope to hear from you soon. Jack |

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
