Every school has its own rules. How many rules are there in your school? At some schools, the students have to wear the uniforms on school days. But many students don't like to wear the school uniforms. They think the uniforms are the ugliest clothes in the world. But the students are not allowed to wear their own clothes at school. So some students draw cartoons or some famous singers on their uniforms. They think it is very boring that everyone wears the same. And it is very unfair that students are wearing the same. But most of the students obey the rules. What do you think of it? Do you like your school uniforms?

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
