My Room
This is my room. Near the window there is a desk. I often do my homework there. You can see some books, some flowers in a vase (花瓶), a ruler and a pen. On the wall near the desk there is a picture of a cat. There is a clock above the end of my bed. I usually put my football under my bed. Of course there is a chair in front of the desk. I sit there and I can see the trees and roads outside.

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
