Dear students,
We live a happy life now. Our parents work very hard. And they buy us lots of beautiful clothes and interesting toys. We can eat different nice food every day. Our parents buy us what we want. But sometimes(有时) they buy too much food. We can’t eat it all. Sometimes they buy too many clothes we don’t need. This is a waste of resources(资源). I think we should say “no” to that. Some people still don’t have enough food in China. We should do something for them.

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
