I have a new bedroom. It's small but nice. You can see my family picture on the wall. It has a bed near the window. I have a cute cat. Its name is Tutu. Oh, no! My cat is on my bed. And my shoes are near the bed. Can you see my panda bag? Yes, it's on the chair. Where are my crayons? Are they in the bag? No, they aren't. They are on my desk. I can sit on the chair and draw pictures. I like my bedroom very much! Do you have a bedroom?

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
