I’m Li Ming. I’m a student in Guangming School. Guangming School is a new school. It’s not very big, but very beautiful. My classroom is on the first floor. It’s next to the computer room. There are 46 students in my class, 22 boys and 24 girls. We have two libraries. They are on the second floor. The big library is for the students. The small library is for the teachers. Our teachers’ office is on the second floor, too. Our teachers are very friendly. We have lunch at school at 12:00. Oh, It’s time to go home. We go home at 4:30 pm.

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
