One year ago, Jim was ten years old. He studied in No. 3 Primary School. He was a good student at school. He listened to the teachers carefully in class. He did his homework quickly.
But he was not a good boy at home. He got up very late at weekends. He didn’t like to help his parents do the housework. He liked watching TV very much. He often read books in bed. His bedroom was very dirty because he often made a mess. So his mum wrote some home rules(规则) for him.
Now Jim begins to clean his room and gets up early. He becomes a good boy at home.

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
