Hello, I’m Mark. Welcome to my new school. It’s big and nice. My classroom is on the first floor. There are forty-two students in my class. Look! This is the teacher’s office. It is next to our classroom, and it’s under the library. That is the music room. It’s on the first floor, too. We can sing and dance in it. On the second floor, there is an art room and a library.

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
