This is my room. Near the window, there is a desk. I often do my homework at it. You can see some books, some flowers in a vase, 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
