I'm Mr Webb. I'm a teacher in Guangming School. The school is very different now. Ten years ago, the school was small with a few students. There were about 10 classrooms in the school. There was no playground. Students had no places to play. They had to play on farms. We had no library. There was only a reading corner in every classroom.
But now, the school is very big. We have a big garden now. In the garden there are many big tall trees and flowers. It's very comfortable to sit under the trees. The new playground is big and beautiful. The classrooms are very big and bright. There are fifty classrooms in the school. There is a big library. The library has many books.

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
