An old man lived with a monkey. His wife was dead and he didn't have any children. He loved his monkey as his child. One day, he put some small boxes in a room. Then he put some apples inside one of the small boxes. When he was doing all this, he asked his monkey to wait outside.
Then he wanted to ask the monkey to look for the apples. Before he went out of the room, he put his right eye to the keyhole (钥匙孔) to see the monkey. But he found himself looking into the eye of the monkey. Outside the room, the monkey was looking at him through the keyhole.

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
