 Many kids have fun ideas about our life in the future. Maybe people will make these things one day. Let's have a look first, go, go, go! This sofa is cool. It can talk to me. It can play music, too. When I feel tired and want to sleep, it will play light music to help me fall asleep quickly. This is the sleeping mode(模式). When I'm reading a book on it, it will get into reading mode. |
 These glasses don't look special. They also have two pieces of glasses. But they are different. They're not only short--sighted(近视) glasses but also a camera(相机) and a telescope(望远镜). If I want to see something far away, touch the glass on the right side, it will make the things far away bigger. If I want to take a photo, just touch the glass on the left side and blink (眨) my eyes. |
 This smart (智能的) classroom looks like a spaceship (宇宙飞船). There is no blackboard or teachers in it. But there are some robots. They can answer any questions. With their help, learning is really easy. What's more, every student has a flying chair. When we press a button (按下按钮) on it, we can travel between home and school. My parents don't need to get up early and drive me to school again. |

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
