Dear Li Jia, How’s it going? We’re doing a project at school about how teenagers around the world relax. I’d really like you to help me, if you can! So, can you tell me: -what is your favorite way to relax? -how long you’ve done it? -how often you do it? -whether relaxing is important and why? Thanks very much, and write soon! Bert |

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
