Hello, I am Linda. I have three teachers. They are Mr. Li, Miss Green and Miss Black. Mr. Li is a new teacher. He comes from the US. He teaches us maths. His class is very interesting. We all like him very much. Miss Green is our art teacher. She is strict, but sometimes she's kind. Miss Black is smart. They are all very nice. We all like them.

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
