It is Saturday. The sun is shining. Danny and his parents are at the corner of the street.
Mum: Danny, this is Huaihai Road. How busy it is!
Danny: Yes, there are a lot of cars and buses on the road. Mum, I’m hungry. I want to go to KFC. It’s over there. It’s opposite the underground station.
Dad: Right, we must cross the road. Look! There are no buses or cars now! Let’s go.
Mum: Wait a minute! There is the red man. We can’t cross the road. Oh, look! The car runs very quickly. It’s dangerous.
Danny: All right, Mum. There is the green man. Let’s go.
Mum: We can’t go this way. We must walk on the zebra crossings.
Dad: But this way is short. OK. We walk on the zebra crossings. We must obey the rules.
Mum: OK. Danny, don’t hurry. Don’t run.
Danny: But I’m very hungry. You must look at the left side first, and then the right side. Because even if the traffic light is red, the cars can turn right.

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
