Joan is a thirteen-year-old boy. He lives in a small village in Qingdao. He studies in a middle school and there are sixty-one students in his class. Forty of them go to school by bike. Twenty of them take the school bus to school. What about Joan? He can’t ride or take a bus because he has no legs. He lost his legs when he was only seven years old. But he isn’t afraid and still smiles at life.
He uses his arms to do everything. Every morning, his mother drives an electric tricycle(电动三轮车) to take him to school. His school is far from their home, so it takes them a long time to get to school. His classroom is on the first floor, so it is easy for him to get into it. All of his teachers and classmates would like to help him at school.

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
