My name is Peter. I'm a blind boy. I've got a pet dog, Allen. He is six years old. His favourite food is meat. He is cute. I like exercise, so every day Allen walks and plays with me in the park. Allen is clever. When we go out, he can push the button（按按钮）with his nose to open the door for me. When we go shopping, he can get the food and put it in the basket. When we go home, he can find the way back easily. Allen is a good helper. I love him and he loves me.

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
