I have two good friends, Tom and Chen Jie. Tom is ten years old. Chen Jie is nine years old. Today is Tom and Chen Jie's birthday. They have two new schoolbags. Look! A Chinese book, an English book, two pens and an eraser are in Tom's schoolbag. What's in Chen Jie's schoolbag? A maths book, a notebook, a pencil box and a ruler. Wow! They have some milk, some bread and some bananas in their (他们的) schoolbags. The schoolbags are so heavy. Who can help them (他们)?

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
