One day a crow (乌鸦) finds a piece of meat. She picks it up in her mouth and flies to a big tree. When she is just going to eat the meat, a fox sees her. The fox comes to the tree and stands under the tree. He looks at the meat and wants to eat it very much.
He says to the crow, “How pretty you are! You are the prettiest bird in the world. All the animals like you. ”The crow is very pleased (高兴的) by these words. Then the fox speaks again, “I can see your beautiful face, but I can’t hear your beautiful voice. Can you sing a song for me?”
This makes the crow very happy. She opens her mouth and sings a song. When she opens her mouth, she drops (落下) the meat. The fox picks up the meat and goes away.

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
