I have a picture of my school. There is a new building in the middle of the picture. There are many flowers and trees near the building. There are twelve classrooms in it. There are twenty-four desks for the students and one desk for the teacher in every classroom. Beside the building, there is a big playground. There are some boys and girls on it, They’re playing happily.
There are some houses next to the building. They are our library and reading rooms. How many windows are there in every reading room? Four. So it’s bright. Now some students are reading. We like our school very much.

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
