Dogs like living with people. They are very friendly. They can do many things for people.
Some dogs help people to look after sheep. Some dogs help people to find the lost children. Some dogs can help the blind, and they are the Seeing Eye Dogs.
Now we can see this kind of dogs all over the world. They are working for the blind. The Seeing Eye dog is strong and easy to train. He helps the blind to walk from place to place. Before a dog becomes a Seeing Eye dog, he must learn in a training school for about three months. First the dog has to learn to sit or stay when he hears the trainer’s call. In his next lesson the dog learns to take his trainer to cross busy streets. The dog has many things to learn. At the end of the training he must take tests. When he passes the tests, the Seeing Eye dog will do things by himself.
The new master (主人) may be a man, a woman, or even a child. It takes the dog and his blind master about a month to learn to work and live together.

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
