I'm Tom. My classroom is very bright and clean. It is not big but it is beautiful. There are fortysix pupils in my class. We are cute and lovely. There are fortysix desks and fortysix chairs. They're for us. There's a TV on the wall. It can help us learn. There's a blackboard in front of the teacher's desk. And there's a flag on the top of the blackboard. There are also many pictures on the wall. They are useful for our study. I like my classroom.

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
