Do you often think of life in the future? Will we study at home? Will we fly to the moon easily? Everyone may have his or her views（观点）about that. Life in the future will be very different from life today. Between then and now, many changes will take place, but what will the changes be?
There will be changes in our food. Maybe no one will eat meat. Instead, people will eat more and more fruit and vegetables. People will stay away from junk food. People will be much healthier.
Computers will be smaller and much more useful. Maybe we will even put the computer into our pockets. There will be at least two computers in every family. And computer studies will be one of the most important subjects at school.
Work in the future will be different, too. Dangerous and hard work can be done by robots. People will work fewer hours than they do now. And they will have more free time for sports, watching TV and traveling.

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
