Mike didn’t go to bed until very late last night. He watched a very interesting film on TV. He had to stay up until eleven forty-five yesterday evening because he wanted to see the end of the film.
This morning, his mother woke him up. He got up and washed his face in a hurry. He didn’t eat anything for breakfast. He ran fast all the way to the bus stop. When he saw the bus coming, he suddenly remembered that he had left his schoolbag at home. He had put his textbooks and homework in the bag last night. He had to go back to get it. When he finally got to school, his English class was already over.

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
