I am Ken. I love stamps very much. Now I have about two hundred stamps. I always go to the post office to buy stamps on the weekend. Sometimes I use my pocket money to buy some stamps,but I can’t buy the most beautiful ones. Because they are very dear. Now I have 50 yuan. It is just enough to buy a new stamp with a panda. So I get ready to go to the post office near my house.

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
