Everyone wants to have good manners (文明举止), but it is not so easy. We must care about everything in life. There is something we should know.
First, say “hello” to people you meet, not only to teachers, but also to your friends and your classmates, and even your neighbors. Second, help others as much as you can. Then everybody will like you. Third, don’t laugh at others. That will be impolite (不礼貌的) and hurt them. Fourth, never ask others about their personal information (个人隐私). If others have something that they cannot say, they will be very embarrassed (尴尬的).
Good manners make things easier. They can help people to get on well with each other. When you are nice to people, they will be nice to you.

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
