Subject | Exchange Visit! |
| Hi there, Li Lei! I'm really excited about going to be at your school for the exchange visit later this year—hope you are too! But the thing is, I really don't want to do the wrong thing while I'm there and especially at the school, so I'm wondering if you could tell me a bit about the rules, about phones, clothes, food... Could you send me a quick email? I'd love to hear from you. Love, Bruce | |

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
