Jim and the twins are in it. What’s in Jim’s hand? There’s a white kite. It looks like a bird. Who’s that man in the red car? Oh, that’s our English teacher Mr Brown. He’s American. Can you see Kate?

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
