Hello, I’m Susan. Welcome to my beautiful school! It’s not big. There is a teaching building(教学楼) and a playground in my school. There are twenty-four classrooms in the teaching building. My classroom is on the first floor. It’s under the teachers’ office. In my classroom, there is a computer on the teacher’s desk. There are two doors, two blackboards, four windows, eight lights and many desks and chairs.
We have a computer room. It’s on the third floor. Next to the computer room there is a music room. I like my school!

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
