If you have a magical pen (神笔), what are you going to do?
Jane, 7 years old: I’m going to draw a robot to help my mother. My mother works hard everyday. And after work, she must do a lot of housework (家务活). If (如果) we had a robot, my mother would have a rest after work.
Jack, 8 years old: I’m going to draw a robot for my grandma. My grandma lives alone (独自). Sometimes she feels lonely (孤单的). The robot can talk with her. And it could look after her. I think she would be happy to live with the robot.
John, 13 years old: Many poor students in the world can’t go to school. And there aren’t enough (足够的) schools and teachers in some places. I’m going to draw many nice schools for poor children. They would have different interesting lessons in my school.

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
