Everyone has his or her hobbies. Collecting stamps is my hobby. I collect many kinds of stamps. Now there are many stamps in my room. I like stamps very much, because the stamps are beautiful and I can learn many things from these stamps. I plan to have many pen pals and I will often write to them. Then I will collect more stamps from the letters.

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
