We played a game yesterday afternoon．We all drew a piece of paper from the box on the teacher's desk，Then we acted one by one．Mike acted like a fish．He asked, “What am I doing?” We answered, “You are dancing.” “No, I'm not dancing. Guess again.’’ ‘‘You are swimming.’’ “Yes, you are right.” After that, Peter walked like a turtle. Tom made a shape of a letter K. We were so happy.

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
