Mr Smith has a farm. His farm is very big. On his farm, he has sixteen cows, twelve horses fifteen pigs and thirteen ducks. There are nine hens and eleven chicks, too. Look, the cows are eating grass. The grass is green. They are fresh(新鲜的). But the horses don't like grass. They like eating hay. The hay is yellow. They are dry, too. What are the pigs doing? They are sleeping in the hey. They are big and fat. They go "Oink, Oink..." They look lovely. I like pink pigs very much. But I don't like black pig.

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
