Liu Tao: I think we should live low-carbon life(低碳生活). To help with the environment, I always walk or ride a bike to school. And use both sides(双面) of every paper and turn off the lights when I leave(离开) the room.
Yang Ling: You're really good! When we do some shopping. We should take cloth(布) bags with us. So that we don't use the plastic bags.
Liu Tao: That's true. Plasct is bad for our Mother Earth. What’s more, I think we should save water and reuse water because our fresh water is limited(有限的).
Yang Ling: Besides, we should pick up the rubbish and throw it into the bin and do something good to our environment.
Liu Tao: Of course. If everyone does something for our Mother Earth, our world will become more and more beautiful.

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
