On a beautiful Sunday morning, there is a sports meeting (运动会) in an animal school. Look! There are many animals in the playground. The monkeys are playing basketball. The rabbits are running. The thin one is running fast. The dogs are swimming in the pool. The black one with big ears is the best. The kangaroos are doing the long jump. They are all good at it. Look the mice under the tree! Oh, they are playing chess. They are very clever. What are the cats doing there? They are looking at the mice. Maybe they want to try it with them. It looks fun. All the animals are happy today.

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
